Abstract

Ferromagnetic Shape Memory Alloy (FSMA) particulate composites are processed using Spark Plasma Sintering (SPS) with various weight fractions of NiTi (51 at% Ni) and Fe powders. Various processing conditions are experimented to obtain the optimum heating rate, holding time and holding temperature in order to maximize relative density, superelasticity and magnetic saturation of the composite. Mechanical strength is evaluated using compression tests.
