The increase of plastic deformation rates on austenite phase created considerable changes in amounts of epsilon (h.c.p.) and alpha'(b.c.c.) martensite, and austenite grains size decreased. Analysis of microstructure and Mossbauer spectra show that the amount of e martensite increased at low deformation rates whereas it decreased at high deformation rate. Besides, Mossbauer spectra of the alloy reveal a ferromagnetic character with a broad sextet for alpha' martensite phase and a paramagnetic character with a singlet for the gamma (f.c.c.) austenite and epsilon martensite phases. In the other hand, the magnetic character of the alloy exhibits a different magnetic order depending on strain rates.eninfo:eu-repo/semantics/closedAccessArticle46196378638310.1007/s10853-011-5585-62-s2.0-80051546545Q1WOS:000292750000026Q2
