High sensitivity on caloric effects induced by stress or magnetic field in a polycrystalline Ni-Mn-In-Co-Cu shape-memory alloy

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.

Magnetic Induction Intensity

With shape memory function of new smart material, the magnetic control properties of magnetic shape memory alloy could be used to fabricate intelligent actuators for vibration control of structures. In order to study its magnetic properties, this text selected Ni53Mn25Ga22 as the material for the research and development of actuator drive, And two MSMA test specimens were prepared for the experimental study under the coupled action of the temperature, preload pressure and magnetic field. The results showed that the strain of MSMA induced by magnetic field decreased with the increase of the preload pressure at constant magnetic field. The deformation performance was best when the magnetic induction intensity was about 0.5T. And the constitutive relations were fitted for the actuator production to lay the foundation for later.
