Phase Equilibria of the Mn-Ni-( Sn,Si,Zn) systems

摘要：

　　The isothermal sections of the Mn-Ni-Sn system at 500℃,the Mn-Ni-Si system at 900 ℃,and the Mn-Ni-Zn system at 400,500 and 600 ℃,were constructed,as shown in Figs.1-5.For the Mn-Ni-Sn system,a new ternary compound with the composition of about Mn22Ni36Sn42 was discovered.This compound adopt hexagonal structure with cell parameter ofa =0.42047(8) nm and c =0.52767(6) nm.In the composition of Mn42Ni30Sn28 for the MnNi2Sn Heusler alloy,the stress-induced martensitic tranformation was identified.The martensitic phase was found to adopt orthorhombic structure.The homogeneity area of the Heusler alloy MnNi2Sn was determined in the present work.
