Microstructural tailoring during solid-state transformation by EPM

摘要：

　　Ni-Mn-Ga ferromagnetic shape memory alloys can generate large output with fast dynamic response at the application of the magnetic field and is considered as a new class of functional materials.Since the martensite of these alloys is highly magnetocrystalline anisotropic,introducing a magnetic field during their martensitic transformation could be an effective way to control variant distribution and realize texturation.In this work,some of our recent results achieved in microstructural and crystallographic texture modification by EPM(Electromagnetic Processing of Materials)during solid-state phase transformations of Ni-Mn-Ga alloys were summarized.Moreover,the entropy change induced by magnetic field in Ni-Mn-Ga melt-spun ribbons were also presented.
