,Ga) [6], Ni-Fe-(Al,Ga) [7-9] and Cu-Mn-(Al,Ga) [10,11] alloys, have been also reported as new FSMAs candidates. The martensitic phase transformation in the ferromagnetic state in Co-Ni-Al alloy system was firstly found by Oikawa’s group [12]. These alloys underwent martensitic transformation from B2-type β-phase to L10-type martensite. The martensitic transformation temperature and magnetic......

that martensitic transformation occurs in weld zone and heat affected zone I and II which are characterized by acicular martensite α′ phase and retained β phase. The transformation of α to β phase is the only phase change process in heat affected zone Ⅲ. The extent of martensitic transformation is relevant to cooling rate in various region of the joint. The microhardness in weld zone is the highest......
by deformation,which reduced the ordering degree of the microstructure,spoiled the reverse path from martensite to parent phase compared with thermoelastic transformation,and imposed resistance on phase transformation through the stress field.关键词:......
