Abstract

Magnetic properties and martensitic transformation response of the Ni ₄₃Co ₇Mn ₃₉Sn ₁₁ metamagnetic shape memory alloy compacts fabricated by pressureless sintering were investigated. The porous specimens sintered at 1173K for 48 h show drastic change of electrical resistivity and magnetization due to martensitic transformation, and the features of magnetic-field-induced martensitic transformation behavior are almost the same as those in bulk specimens. In the porous specimens, the large metamagnetic shape recovery ratio over 40% was observed at 320K with the application of 8 T magnetic field.
