Special features of plastic strain in amorphous iron-base alloys deformed locally in the process of isochronous annealing are studied. It is shown that two types of defect appear on the surface near stress concentrator, namely, shear bands in the form of semirings and in the form of rays. The general tendency of the behavior of shear bands in annealing is determined. As a rule, the process of formation and evolution of semiring shear bands intensifies inconsiderably at low annealing temperatures and decelerates abruptly after 600°C. 相似文献
