Abstract

The mechanical properties of the sintered compacts made of the Fe-0.5mass%Cr-0.2mass%Mn-0.2mass%Mo prealloyed powder (JIP® 5CRA) have been investigated. Tensile strength and hardness of the 5CRA material increased with the increases of addition of Cu and graphite, respectively. 5CRA-2.0mass%Cu-1.0mass%Gr material showed high-strength equivalent to that of the Fe-4.0mass%Ni-1.5mass%Cu-0.5mass%Mo-0.6mass%Gr material. Microstructure of the sintered compact of the 5CRA material containing Cu was consists of fine pearlite and some bainite. High-strength of the 5CRA material would be obtained by the effect of solid solution strengthening due to Cu addition and finer pearlite with graphite addition.
