Abstract: abstract:The microstructure and magnetic property of a cold rolled Ni72Cr16Fe8 alloy have been studied as a function of its plastic deformation from 0 to 75%. The saturation magnetization decreases as the strain increases. The Curie temperature is also decreased from 183 to 178 K for samples with the deformed strain from 0 to 75%. The decrease of the magnetic properties could be related to the effects of the variation of its microstructure and the deformation induced crystal defects, such as vacancies and dislocations. The acicular (needlelike) twins, which is associated with the nonlinear λ-type electrical resistivity, were found in the specimen of 75% deformed strain.
