Abstract The metastable austenite was transformed to martensite by prestrain tension of SUS304 stainless steel to study the influence of transformed martensite on its subsequent work��hardening behavior under the uniaxial tensile condition. The X��ray diffractometer (XRD) was employed to detect the transformed martensite. Results showed that the volume fraction of transformed martensite increases with increasing prestrain. The pre��transformed martensite in the microstructure remarkably affects the deformation behavior of the steel, and the strength increases and the elongation decreases. The work��hardening curve of prestrained specimens observably changes with true strain. The work��hardening exponent n of stainless steel decreases with the increase of pre��transformed martensite. The achievement is a significant contribution to the process design during pressing.
