- Abstract
- The deformation behavior of Fe-17Mn-0.02C steel containing E >-martensite within austenite matrix has been investigated via in-situ neutron diffraction study at 298 K and 77 K. Based on the analyses of changes in phase fraction and lattice strain, it has been shown that the steel shows the deformation-induced phase transformation of austenite -> E >-martensite -> alpha'-martensite and the direct transformation of austenite -> alpha'-martensite at both temperatures. However, the kinetics of such transformations vary with temperature, resulting in a higher and more persistent work hardening at 77 K than at 298 K.
