Microstructures and mechanical properties of sintered precipitation hardening stainless steel compacts by metal injection molding

摘要

The effect of debinding conditions on microstructures and mechanical properties of the sintered 17-4PH stainless steel compacts made by injection molding were investigated.And also the influence of heat treatment on mechanical properties of the sintered comapacts was examined.The specimens were made by injecting the mixture of gas-atomized 17-4PH stainless steel powder and a polyamide binder into a metallic mold.
