英文摘要	This study investigated the microstructure, phase transformation and mechanical property of Ni-Mn-Ga particles/Mg composites with a strong interfacial reaction between the particles and the matrix. The strong interfacial reaction was related to the large surface area and energy per unit volume of the flaky shape Ni-Mn-Ga particles that favors the reaction between the particles and matrix. The martensitic transformation behavior was largely weakened due to the interfacial reactions and thus the reduced volume fraction of Ni-Mn-Ga particles. The composites exhibited a much improved compressive strength and ductility in comparison with that of the Ni-Mn-Ga alloy. The compressive plasticity of the composites was decreased when the Ni-Mn-Ga particle content exceeded 40 wt%. In comparison with the Mg-composites with large size Ni-Mn-Ga particles, the composites with small size particles would have a much stronger interfacial reactions, which was detrimental to the phase transformation and mechanical ductility of the composites. The investigation results in this article could provide a reference for the design and preparation of the particles reinforced metal matrix functional composites. (C) 2015 Elsevier Ltd.
