Transformation temperature decreases with field increasing at 0.9 K / kOe. It was found that annealing at 1023 K for 50 hours leads to a decrease of width (about twice) of thermal hysteresis of martensitic transformation. Alloys such as Ni-Mn-In characterized by a significant volume effect of the martensitic transition (significant difference in specific volumes of high-temperature and low-temperature phases), which leads to the generation of a large dislocation density (phase hardening ) in both phases under cyclic temperature changes and to its Product Description popup.authors Кокорин В.В.
