Evolution of microstructure, mechanical and magnetic properties of electrodeposited 50Ni-Fe alloy foil after thermal treatment

摘要

In order to expand the application of the electrodeposited Ni-Fe alloy foil, their mechanical and magnetic properties were studied after heat treatment.The development of grain growth during annealing was in-si-tu online investigated using a heating stage microscope, and the texture was analyzed via X-ray diffraction (XRD) and electron back-scattered diffraction (EBSD).The results indicated that abnormal grain growth usually occurred during annealing at 1000-1050℃.The {111} oriented grains preferentially grew as the annealing temperature and holding time increased.The plasticities of the electrodeposited Ni-Fe alloy foils after heat treatment were better than those of the original samples.The excellent ductility was obtained without a loss in magnetic properties after annealing at 1100℃ for 6 h.
