Effect of stress-induced martensite ageing on the one-way and two-way shape memory effect of [0 1 1]-oriented TiNiCu crystals under tension

In this paper, for the first time, we found that at tension value of the one-way shape memory effect (SME) was 9.9% at external stresses of 250 MPa of the [011]-oriented Ti50Ni40Cu10 alloy (at%) crystals, which exceeds the theoretical value 7.14% for the B2-B19-B19'martensitic transformation (M...

520 3 |a In this paper, for the first time, we found that at tension value of the one-way shape memory effect (SME) was 9.9% at external stresses of 250 MPa of the [011]-oriented Ti50Ni40Cu10 alloy (at%) crystals, which exceeds the theoretical value 7.14% for the B2-B19-B19'martensitic transformation (MT) under tension. It was shown that stress-induced martensite ageing (SIM-ageing) creates conditions for the realization of a tensile two-way SME (TWSME) of 2.5% and does not decrease the value of the one-way SME.
