摘要：

The production of a new Powder Metallurgy (PM) tool steel obtained by Spark Plasma Sintering (SPS) powder blends of AISI H13 and AISI M2 is considered. The objective is to obtain a product, the properties of which could be modulated on the basis of the specific application considered. Sintering powders of four blends were obtained (20% H13-80% M2, 40% H13-60% M2, 60% H13-40% M2, and 80% H13-20% M2). Density, hardness, fracture toughness, and wear resistance were evaluated. Increasing the fraction of M2 improves hardness and wear resistance. Fracture toughness is correspondingly lowered. The toughness of H13 rich blends was negatively affected by the high oxygen content in the base powder.
