Purpose: Development of a new generation tool materials on the basis of M2 high speed-steel reinforced with the carbides. Application of powder injection moulding as a manufacturing method gives the possibility to produce these materials in a mass scale with relative low cost of production. Design/methodology/approach: Powder Injection Moulding, solvent debinding, sintering, thermogravimetric analysis, microstructure examination, porosity examination, Findings: To manufacture the proposed new tool materials was used powder injection moulding processes. It was found out based on the investigations carried out that the powder injection moulding method is suitable for fabrication of M2 high speed-steel reinforced with the carbides. The main advantage of the presented experimental tool materials is the wide sintering window being only about 5°C oftentimes in case of the high-speed steels; whereas, it is about 40°C for the investigated material. Practical implications: Application of powder metallurgy and especially powder injection moulding to manufacturing of high speed-steel reinforced with the carbides gives the possibility to obtain tool materials with the relative high ductility characteristic of steel and high hardness and wear resistance typical for cemented carbides. Originality/value: The powder injection moulding gives the possibility to fabricate carbide alloyed composite which, with their structure and mechanical properties, fill the gap in tool materials between the high-speed steels and cemented carbides.
