| Abstract Scope |
This work demonstrates the roles of hot-rolling processes in microstructure and mechanical properties in Fe-0.21C-2.04Mn-1.04Si-1.10Al-0.064Nb-0.2Mo (in wt.%) alloy. Two strong and ductile transformation-induced plasticity steels (UTS 980 MPa x EL 25 % and UTS 1180 MPa x EL 20%) with distinguishable stress-strain behaviors were developed. Dynamic ferrite and granular bainite respectively were applied into these two steels. Nano/microstructures, strengthening mechanisms, and behaviors of transformation-induced plasticity in two steels were elucidated based on investigations of electron backscattering diffraction, transmission electron microscopy, and X-ray diffraction. The metallurgical principles can be applied to fabricate new transformation-induced plasticity steels directly by hot-rolling processes. |
