- Abstract
- The tensile behavior of intercritically annealed Fe-12 pctMn-0.3 pctC-2 pctAl and Fe-12 pct Mn-0.3 pctC-3 pctAl steel was studied by means of in situ neutron diffraction and microstructural analysis. The in situ neutron diffraction measurements showed that the ferrite had a much higher yield strength and lower work hardening rate as compared to the austenite. The strain hardening of the austenite was controlled by deformation twinning and strain-induced transformation, occurring in succession. This TWIP + TRIP effect acted as an effective plasticity-enhancing mechanism which increased the work hardening rate. (C) The Minerals, Metals & Materials Society and ASM International 2016
