1 SINTERABILITY OF HIGH-SPEED STEELS, M3/2 AND Romário Mauricio Urbanetto Nogueira CEFET/PR UNED/MD César Edil da Costa DEM-CCT/UDESC Keywords high speed steels, powder metallurgy, sinterability. Abstract: High-speed steel (HSS), widely used for tools, is characterised by excellent hardness, wear resistance, and high-temperature properties. Sintering of high-speed steels has been studied extensively in conventional powder metallurgy (P/M). The most promising advantage of P/M lies on cost saving when compared to the wrought production route. However, due to composition complexity, sintering practice is extremely sensitive to its parameters. The densification process, microstructure development and composition controls are the major problems to be solved. In this work, a study is presented on the sinterability and densification of high speed steels (, M3/2 and composition) produced by conventional powder metallurgy (P/M). Material samples were compacted uniaxially at 700 MPa followed by sintering in different temperatures using protecting atmosphere (N 2-8%H 2 ). The sintering temperatures were determined by the dilatometry curves. The materials were characterised by measurements of the density hardness and microstructural analysis through optical microscopy. 1.Introduction High-speed steels (HSS) can be divided into groups: conventional and P/M HSS (manufactured by powder metallurgy routes). Conventional HSS are produced hightemperature metallurgical procedures (melting in electro-arc furnaces, continuous or discontinuous casting into billets or ingots, followed by forming with hot rolling and/or forging)[1]. Sintered high-speed steels have a well-defined field of application because of their good properties in comparison with wrought HSS [2]. However, these properties depend on the manufacturing process. When a very high density is needed in order to get higher mechanical properties, several routes can be taken, e.g. liquid phase sintering, spray forming and hot isostatic pressing (HIP). Among these routes, HIP allows one to obtain pre-forms of HSS free of porosity and with a small size of carbides. Although these materials have good properties, they are more expensive than wrought HSS because of the higher cost of using the HIP route [3]. Another widely used P/M manufacturing method for HSS is powder consolidation by uniaxial cold compaction and sintering of green compacts. In this case, lower-quality but cheaper water-atomized powders are used. Water-atomized powders have irregular shaped particles. Therefore, these powders are particularly appropriate for uniaxial cold compaction after an additional soft de-oxidation annealing. Water-atomized HSS powders are coldpressed into green compacts of complex shapes with a high-production-rate mechanical or 1

2 hydraulic press. Sintering of the green compacts in vacuum or a protective/reductive (N 2-8%H 2 ) atmosphere is then performed. The main advantage of this PM procedure is a large-scale production of complex shaped products with narrow dimensional tolerances and almost without any additional machining costs. Another advantage of this PM procedure is the flexibility to prepare different powder mixtures. Admixing of different hard/soft particulate phases to the basic high-alloyed HSS powder is possible. The formed powder mixtures can contain fine particles of carbides, oxides, sulphides or fluorides (for example: NbC, TiC, A , MnS, CaF 2, etc.) enabling the synthesis of special composite materials with target properties for a precisely defined application (e.g.: improved wear resistance, higher thermal or corrosion resistance, better machinability and self-lubricity, etc.) [4,5]. High-speed tool steels are used extensively for cutting and forming tools, as well as for wear parts, because of superior mechanical properties and abrasion resistance. However, wrought tool steels exhibit a strong tendency to segregate during solidification in a mold, resulting in a coarse, no uniform microstructure with variation in chemical composition. This tendency limits toughness, creates heat-treating problems, and decreases grindability. Powder metallurgy processing is being used increasingly to overcome these problems advantages of P/M high-speed steels include superior strength and toughness [6]. In comparison with wrought high-speed steels (HSS), powder metallurgical (P/M) HSS have a more uniform microstructure with fine and well-distributed carbides, which prevents coarsening or a skeleton-type eutectic surrounding the ferrite grains. P/M HSS have no segregation of alloying elements, at microstructure levels nor at structural levels [7]. Other advantages of these processes in relation to conventional methods include less material waste, isotropic mechanical properties, near net shape [8]. Microstructural problems in P/M HSS could have their origin in an inadequate sintering temperature that promotes undesired melts and a subsequent eutectic network on cooling. However, with an optimal sintering process, P/M HSS will show better characteristics than the same grades of HSS made by conventional methods, and some HSSs can only be obtained by P/M methods [7]. 2 - Experimental procedure It was studied in this work the sinterability and the densification of the high-speed steels type, M3/2 and (Table1). For the determination of the sintering temperatures dilatometry experiments were realized. The specimens were obtained by uniaxial cold compaction at 700MPa, and the dilatometry was realized with heating rate of 5 ºC/min until the maximum temperature of 1290ºC, in the N2 atmosphere. After the analysis of the curves obtained in these experiments it was decided to work with the sintering temperatures with of 1150 ºC, 1200 ºC, 1225 ºC, 1250 ºC, 1270 ºC, and 1285 ºC landing, being realized in tubular furnace with protecting atmosphere of gas special mixes (N 2-8%H 2 ) with rates of heating of 10 ºC/min and time in the temperature of 60 minutes landing. For determination of the density the Archimedes method was used and the mechanical properties were measured by the Vickers hardness HV15. Analysis of microstructure was realized through the optical microscopy. 2

Analysis and discussion of results We can verify through the analysis of the dilatometry curves (Fig.1) that the beginning of the contraction for each type of HSS happens in different temperatures, for HSS it happens at temperature of 1115ºC and of HSS M3/2 at 1190ºC, while HSS contraction at 1064ºC. We observed from the dilatometry curves that the rate of maximum contraction for and M3/2 are located between the temperatures of 1255ºC and 1288ºC. The maximum contraction for happens between the temperatures of 1200ºC and 1285ºC, however in at temperature of 1250ºC happens a landing transition. M3/2 Fig.1 Dilatometry of high-speed steels, M3/2 and. The relative density of HSS (Fig. 2) shows that for the sintering realized between the temperatures of 1150ºC and 1250ºC the relative density approximately 80%. The sintered in temperatures more than 1250ºC happens an increase reaching values more than 90% of relative density between the temperatures of 1270ºC and 1285ºC, not having an increment of the densification with the increase of the temperature. For HSS M3/2, the sintered realized at temperatures of 1150ºC and 1200ºC the relative density is close to 80%. The relative density reaches superior values to 90%, with the increase of the temperature above 1200ºC. It is observed for HSS that realized at temperature of 1150ºC the relative density for the sintering reaches about 75% and for the temperatures above 1200ºC the relative density reaches close values to 90%. All of the studied HSS have a similar behavior with a landing of maxim densification after that; it will not happen alteration in the densification. 3

Is observed with the study of the behavior of the materials in different sintering temperatures that for (Fig.3), at temperatures between 1150ºC and 1250ºC the hardness is about 200 HV15, and at temperatures above 1250ºC happens an increase of the hardness is values close to 500 HV15, between the temperatures of 1270ºC and 1285ºC, being in agreement with an higher densification with the temperature increase. It can be observed for M3/2 (Fig.3) that for the sintering realized at temperatures of 1150ºC and 1200ºC the hardness is close to 200 HV15, at temperature of 1225ºC it happens an increase of the hardness reaching more than 600 HV15 it happens at temperatures between 1250ºC and 1285ºC a decrease of the hardness for medium values of 450 HV15. It happens in these higher temperatures structural transformations that the final properties. The hardness in HSS the (Fig.7), at temperatures will be reduced 1150ºC to 1225ºC, grows in values close to 200 HV15, until a value of hardness of 600 HV15. It happens at temperatures 1250ºC, 1270ºC and 1285ºC a decrease of the hardness close values to 500, 420 and 400 HV15 respectively, presenting a similar behavior to HSS M3/2. Hardness Vickers-HV Hardness Vickers M3/ ºC Fig.3 - Hardness of high-speed steel, M3/2 and in function of the sintering temperature It is observed in the microscopy analyzes of HSS that until the temperature of 1250ºC the microestrutural has a lot of porosity and homogeneous distribution of small carbides, at temperatures of 1270ºC (Fig.4) and 1285ºC the microstructure doesn't have significant porosity and there is a growth of the carbides (Fig.5). The microstructure is similar to for HSS M3/2 at temperatures of 1150ºC (Fig.4) and 1200ºC, with a distribution of characteristic porosity of the metallurgy of the powder processes and presence of small carbides. There is a decrease of the porosity and the M3-2 4

The process continues at temperature of 1270ºC as well as the carbides coalescing. Also it happens the beginning of the eutectics phases at temperature of 1285ºC (Fig.5). It is observed that for HSS, at temperature of 1150ºC (Fig.4) the same behavior of the high-speed steels and M3/2 while at temperature of 1200ºC (Fig.4) it happens a maxim densification of the material and the presence of small carbides distributed in the matrix. It is observed at in the temperature of 1225ºC a growth of the carbides. It happens the growth of the grains at temperatures of 1250ºC, 1270ºC and 1285ºC (Fig.5) C 1150 C 1150 C 1270 C M3/ C 1200 C Fig.4 - Microstructures of the high-speed steels, M3/2 and in the minimum temperature of sintering and at temperatures in that it is obtained the maxim density for each material.

It happens an increase of the densification of HSS as the increase of sintering temperature arriving to landings. It doesn't happen significant increase of the final density above that. For HSS compacted uniaxially to 700MPa and after sintered in furnace with protecting atmosphere of gas N 2-8%H 2, the point of view of the largest density and the largest hardness the best to sintering of the HSS is 1285ºC. The best temperature to HSS M3/2 and is 1225ºC all of that can be verified in the microstructure analysis. The increase of the sintering temperature begins the growth of the grains and the carbides coalescing, causing excessive deformations of the specimens and the consequent decrease of their properties. 5. references [1] B.
