Lopez Del Castillo, J. Herñaez, B. Mellor] The effect of thermal cycling on the thermoelastic martensitic reaction and stress cycling on stress induced martensite formation and pseudoelasticity have been studied in alloys in the Cu-Al-Mn system. The martensite to high temperature phase start and finish transformation temperatures,A s andA f, of alloys quenched from 850‡ C were considerably higher than after repeated thermal cycling. The excess vacancy concentration present after quenching is postulated to enhance low temperature ordering reactions in these alloys through defect assisted diffusional mechanisms and so stabilize the martensite leading to higherA s andA f temperatures. Stress cycling of aΒ phase alloy increased pseudoelastic recovery and decreased the stress necessary to form stress induced martensite. Ageing specimens at room temperature after stress cycling was found to increase considerably the stress required to form stress induced martensite on subsequent stress cycling. Both pseudoelastic and shape memory recovery were observed in a martensitic alloy. Chapman and Hall Ltd., 1986 Lopez Del Castillo C.
