Abstract

The microstructural, phase transformation and magnetic properties of Ni - Mn - Ga alloy fabricated using the spark plasma sintering method have been investigated. The results show that both the as-sintered and annealed sintered specimens exhibit typical martensitic transformation behaviours. The martensite of the sintered specimen after annealing exhibits a ferromagnetic nature. Moreover, study of the fracture surface indicates that the transgranular fracture contributes to the higher ductility of sintered Ni - Mn - Ga alloy. In addition, the transformation strain in sintered Ni - Mn - Ga alloy is studied for the first time.
