Temperature hysteresis of martensite transformation in aging Cu–Mn–Al alloy

Effect of chemical ordering annealing on martensitic transformation and superelasticity in polycrystalline Ni–Mn–Ga microwires

“…Annealed microwires have a smaller peak to peak hysteresis ($10.6°C) compared with the as-extracted ones ($12.2°C), which is related to two energy dissipative processes: (1) the stored elastic strain energy is dissipated when the coherency strains of martensite-austenite interface relax or bypasses dislocations or precipitates [33,34], (2) frictional work is dissipated to overcome the resistance to interfacial motion. Both dissipation processes may increase the MT hysteresis.…”

Molecular dynamics simulation study of microstructure evolution during cyclic martensitic transformations

“…The interactions of moving interfaces with such defects were investigated in Kustov et al (2004) and Pé rez-Landazá bal et al (2006) for Cu-based alloys. The effect of aging on the temperature hysteresis in such alloys is documented in Kokorin et al (2002). All these works refer to a strong relationship between the evolution of microstructural morphologies and the thermodynamic properties of the materials, indicating a history-dependence of the phase diagrams.…”

Transformation Volume Effects on Shape Memory Alloys

“…This feature of the transformational behavior of aged alloys is indirectly confirmed by the experiments in [67][68][69][70].…”
