The coherent nanoparticles inherited by martensite crystals change parameters of martensitic transformation. This paper considers a non-monotonic behaviour of temperature hysteresis of martensitic b1 g? transformation at the increase of ageing time at the fixed temperature. The effect of Cu–Al–Mn alloys ageing regimes on superelastic behaviour of austenitic and martensitic phases are studied as well. The maximum value of superelastic strain in austenite state corresponds to a minimum width of martensitic-transformation temperature hysteresis for Cu–Al–Mn alloys. The presence of precipitation-phase nanoparticles increases a strain for the martensite formation in Cu–Mn–Al alloys under mechanical-stress field.
