Matrices of FGM/FGCM materials can be developed by aluminium powders, high speed steel powders, and nickel and titanium alloys powders or by hybrid steels powders [1-4].
Matrix of Ancorsteel 2000/A2000 and Ancorsteel 4600/A4600V adopted in this work for development of FGM/FGCM materials is aimed to replace the conventional general purpose oil hardening tool steel such as 1.2358/60CrMoV18-5; (0,60% C; 4,5% Cr; 0,50% Mo; 0,20% V); 1.2363/X100CrMoV5 (1% C; 5,3% Cr; 1,10% Mo;0,25% V); 1.2842/90MnCrV8 (0,90% C; 2,00% Mn; 0,40% Cr; 0,105% V) or even alloyed steels: 1.2379/X153CrMoV12 (1,55% C; 12,00% Cr; 0,80% Mo; 0,90% V) and 1.2436/X210CrW12 (2,10% C; 12% Cr; 0,80% W) (www.doerrenberg.com).
The mechanical properties of hard powders used for reinforced ferrous/non- ferrous matrices are presented in Table 1 [6] Table 1.
