Microstructure and mechanical properties of TiN precipitation hardened 316L stainless steel produced by hot extrusion of rapidly solidified powder

Creators

Description

A precipitation hardened Ti-modified 316L stainless steel has been prepared by extrusion of nitrided rapidly solidified powder. The microstructure and mechanical properties of rapidly solidified powder, internally nitrided powder and extruded bulk material have been investigated. It has been found that the microstructure of extrudates consists of fine austenite grains and uniformly dispersed titanium nitride particles, as well as subgrains with dislocation tangles. Finely disperesed nitride particles suppress the grain growth by pinning the grain boundaries during recrystallization. A signigicant improvement of tensile properties, hardness and creep properties is obtained, as compared to conventional 316L stainless steels. (authors)
