Purpose: This study investigated the deformation effect in variation of α′-martensite volume fraction and its microstructural characteristics in an austenitic stainless steel AISI 304. Design/methodology/approach: The study was fulfilled through magnetic analysis with Vibrating Sample Magnetometer (VSM) and transmission electron microscopy (TEM). Findings: The presence of austenite, ε-martensite and α′, and that the nucleation of ε-martensite occurs in stacking faults, grain boundaries and accumulated dislocations in grain boundaries. Already α′-martensite nucleates in stacking faults, twinning edges, deformation bands and mechanical twinning. In addition, the magnetic martensite takes shape directly from the austenite. Research limitations/implications: A suggestion for future research is to increase the number of samples for deformations larger than 0.30 equivalent strain, due to the significative percentage of α′-martensite from this strain. Practical implications: A crescent parabolic behavior in relation between percentage of α′-martensite and equivalent deformation was observed by VSM. The increase of equivalent deformation increases the austenite transformation in α′-martensite. Originality/value: The behavior in relation between percentage of α′-martensite and equivalent deformation, and the study of α′-martensite nucleation.
