Two-way shape memory effect and mechanical properties of Pulse Discharge Sintered Ni2.18Mn0.82Ga

摘要

Mechanical and shape memory properties of a polycrystalline Ni2.18Mn0.82Gaalloy prepared by a PDS (Pulse Discharge Sintering) method were investigated.It was found that the material demonstrates the two-way shape memory effectafter a loading - unloading cycle performed in the martensitic state, i. e.essentially without special training. The samples exhibiting the two-way shapememory effect show a significant enhancement in the magnitude ofmagnetic-field-induced strain.
