The material under investigation was a commercial austenitic stainless steel SS 1.4307 (EN) equivalent to AISI 304L. The samples of SS 1.4307 were rolled, achieving a 56, 60 and 62% reduction in thickness. The plastic deformation reduced austenite phase at the expense of the newly formed martensite phase. The volume fraction of austenite phase, crystallite size and lattice strain were calculated from X-ray line broadening. The X-ray diffraction measurements were carried out in a Philips X-Pert diffractometer using KαCu radiation.
