Effects of Ni Addition on the Microstructures and Magnetic Properties of Fe_70-xPd₃₀Ni_xHigh-Temperature Ferromagnetic Shape Memory Alloys

Abstract

This study investigated the effects of adding a third alloying element, Ni, to create Fe 70-x Pd 30 Ni x (x = 2, 4, 6, 8 at.% Ni) ferromagnetic shape memory alloys (FSMAs). The Ni replaced a portion of the Fe. The Fe 70-x Pd 30 Ni x alloys were homogenized through hot and cold forging to gain a ~38% reduction in thickness, next they were solution-treated (ST) with annealing recrystallization at 1100
