TL;DR: In this article, a micro-mechanical model based on reversible thermodynamics was modified to account for plastic relaxation of coherent transforming interfaces, and the predictions account for the growing hysteresis with increasing external stress.

TL;DR: In this paper, the potential role of detwinning on the recoverable NiTi alloys was investigated both theoretically and also with temperature-cycling experiments, and it was shown that partial detwinning of martensite has occurred in both the solutionized and overaged NiTi specimens.

TL;DR: In this paper, the authors used SIM-aging to increase the martensite start temperature by about 130°C for a Co-Ni-Ga shape memory alloy and showed cyclic actuation stability at elevated temperatures.

TL;DR: In this paper, the role of nitrogen content on the stress-strain response of Hadfield steel (HS) single crystals under compressive loading was studied and a visco-plastic self-consistent (VPSC) model was modified to account for precipitation and twinning length scales in HS with 1.06 wt pct nitrogen.

TL;DR: In this article, a CoNi-Ga shape memory alloy has been studied by neutron diffraction in different conditions, i.e., as-grown austenite, quenched martensite, heat-treated Austenite and stabilized stress-induced martensites.
