Purpose: Development of a new generation tool materials on the basis of M2 high speed-steel reinforced with the mixture of carbides and with their structure and mechanical properties, fill the gap in tool materials between the high-speed steels and cemented carbides. Design/methodology/approach: Powder metallurgy, powder injection moulding, sintering, sinter hardening, heat treatment, microstructure and porosity examination, X-ray analysis, TEM, bending test, hardness test. Findings: Powder injection moulding processes were used to fabricate the proposed carbide alloyed composite materials. The addition of hard particles increase hardness after heat treatment and slightly reduces the ductility of these materials. Compared with M2 high-speed steel the bending strength of carbide alloyed composite decrease. The main advantage of the presented experimental tool materials is application of powder injection moulding to produce tool materials in a mass scale with relative low cost of production. Moreover the cost of production reduce application of sinterhardening. Practical implications: Application of heat treatment and especially sinterhardening to improve the mechanical properties of presented experimental tool materials gives the possibility to obtain tool materials with the relative high ductility and high hardness typical for cemented carbides. Originality/value: The essential advantage of the investigated injection moulded material and sintered is the broad range of the optimum sintering temperatures and the relatively small effect of the sintering temperature growth on the carbides growth makes using the industrial heating equipment possible.
