Improvement of shape recovery by controlling the microstructure and mechanical properties in a thermomechanically-treated Fe-based alloy

Autor: Hamidreza Koohdar, Nasim Nayebpashaee, Hamid Reza Jafarian

Publikováno v: Journal of Materials Research and Technology, Vol 29, Iss , Pp 530-539 (2024)

In this research, the effects of thermomechanical treatment including heavy cold rolling and post-deformation annealing on the improvement of shape recovery in an Fe–9Ni–7Mn (at.%) martensitic alloy were investigated. Experimental results showed
