The effect of constant-strain aged and unaged on microstructure, martensite transformation, Curie temperature and magnetic field induction strain of Ni53Mn23.5Ga23.5ferromagnetic shape memory alloy was investigated in detail. The results show that reverse martensitic transformation temperatures of constant-strain aged sample slowly decrease, which martensitic transformation temperatures almost unchanged. In addition, Curie temperature of constant-strain aged sample is almost maintains consistent with solution-treated sample, but slowly increases saturation magnetization of constant-strain aged sample than solution-treated sample. Finally, the sample of constant-strain aged sample showed a larger magnetic field induction strain of 402 ppm.

Melt Spun

A non-stoichiometric polycrystalline Ni50Mn27Ga23 magnetic shape memory alloy was prepared by melt-spinning technology. The effects of melt-spinning on the martensitic transformation and magnetic-field-induced strain (MFIS) of the melt-spun ribbon were investigated. The experimental results show that the melt-spun ribbon undergoes the thermal-elastic martensitic transformation and exhibits the thermo-elastic shape memory effect. But the martensitic transformation temperature decreases and Curie temperature remains unchanged. A particular internal stress induced by melt-spinning made a texture structure in the melt-spun ribbon, which made the melt-spun ribbon obtain larger transition-induced strain and MFIS. The internal stress was released under cycling of magnetic field. This resulted in a decrease of MFIS of the melt-spun ribbon.

Two Peaks

We report the effect of shorttime vacuum annealing, during 10 minutes at 923 K, 973 K, 1023 K and 1073 K, on magnetostructural properties of as-quenched ribbons of Ni45.5Mn43In11.5 Heusler alloy. The martensitic transformation is strongly sensitive to annealing treatments. The martensitic phase starting temperature is significantly shifted from 239 K towards higher temperatures around 370 K. It suffers a break down in two peaks when a field equal or higher than 500 Oe is applied to the as-quenched sample. This effect is not detected in the transformation of annealed ribbons but its signature can be observed at low temperature. Moreover, under high magnetic field up to 30 kOe temperatures associated with both martensitic and reverse transitions do not change for annealed samples, meanwhile the magnetization difference between austenite and martensite increases with the field. Nevertheless, it almost remains unchanged in the as-quenched ribbon.

The Magnetic Field

This paper reports an experiment equipment which is used as reversibility research of magnetically controlled shape memory alloy (MSMA). The vibration detection is done based on dynamic reversibility of MSMA. The results show that MSMA will induce Martensitic transformation in the magnetic field. The characteristics of rapid dynamic response, high sensitivity and reversibility are found. The material is of a bright future of application in sensors and self-sensing actuator (SSA) field.
