Abstract
In the present work, the effect of pre-strain on martensitic transformation of Ni43Mn43Co7Sn7 (at.%) alloy was investigated. The results show that Ni43Mn43Co7Sn7 alloy undergoes a martensitic transformation at 288 °C upon cooling. The thermal cycling does not affect the transformation behavior of the alloy, indicating the good thermal stability. The reverse transformation of the deformed martensite is pre-strain dependent. When the pre-strain is higher than 7.5%, the reverse transformation occurs in two-stage manner upon first heating due to the nonuniform martensite deformation. In contrast, during the first martensitic and second reverse transformation, the pre-strain shows little effect on the transformation temperatures.
