Abstract
Porous FeCrN stainless steel has excellent corrosion resistance, biocompatibility and mechanical properties matching human bone because of non-nickel and manganese, which is a new direction of medical implants. In this paper, FeCrN stainless steel with porosity of 28.21%-60.16% was prepared by powder metallurgy method. The microstructure, pore morphology and mechanical properties of porous stainless steel were analyzed by means of XRD, SEM, EDS and compression test. The microstructure of porous stainless steel is mostly austenite + ferrite. With the increase of porosity, the compressive yield strength, compressive strength and elastic modulus of the material decrease.
