Effects of twin intersection on the tensile behavior in high nitrogen austenitic stainless steel

摘要

The effects of microstructure evolution with different amount of cold compression on the mechanical behavior were investigated in high nitrogen austenitic stainless steel. Maximum tensile strength and 0.2% yield strength were increased with the increase of cold compression percent. Twin intersection in two different crystallographic orientations was observed when the specimen was cold-compressed more than 30%. Twin intersection resulted in the increase of strain hardening exponent and the reduction of strain at maximum tensile strength.
