In situ transmission electron microscopy study of martensite boundaries movement on cooling and heating of the NiTi shape memory alloy

A. Sibirev et al.

Summary: This study examined the peculiarities of the movement of martensite interfaces in a NiTi alloy during the forward and reverse transformations using in situ transmission electron microscopy. The results showed that the sequence of martensite shrinking on heating was not the opposite of the sequence of martensite formation on previous cooling, and the formation sequence during the second cooling was different from the first cooling. Additionally, dislocations did not hinder martensite formation nor aid in nucleation and growth.

Orientation dependence of elastocaloric effect in Ni50Mn30Ga20 single crystals

N. Yu. Surikov et al.

Summary: This study investigated the orientation dependence of the elastocaloric effect and superelasticity in Ni50Mn30Ga20 single crystals undergoing martensitic transformations. The adiabatic temperature change delta Tad was weakly dependent on orientation, while stress hysteresis delta sigma showed significant orientation dependence. These findings have implications for the practical efficiency of using the material as a solid state cooling device.
