Abstract: CuAl18Mn10.5(at.%) shape memory alloys and NiMn25Ga22(at.%) magnetic shape memory alloys were combined by powder metallurgy, and temperature and magnetic field mulriple apperceiving new type functional composite material was explored. After sinter and resolve treatment, most part of the composite is composed by the two independent patents phases and martensitic phases of the alloys. Some of the interface of the composite got diffusing reaction of the atoms between the two alloys, XRD result shows that some new phase such as Ni3Al was obtained by diffusing reaction on the boundary. The shape memory effect (SME) induced by temperature and magnetic field reduce due to the volume fraction of the two alloy powder, and inter-stress brought during fabrication of the composite also consume SME by stress-induced martensite.
