Abstract

The plastic deformation of Fe-3%Si alloy single crystals made from the melt is studied by the method of etching of dislocations. At a room-temperature and at static stress deformation by slip occurs in the 1/2〈111〉 directions along planes of maximum resolved shear stress. The plastic properties are determined by the motion of screw dislocations which cause the broadening of slip bands.

Abstract

При помощи метода травления дислокаций исследуется пластическая деформация монокристаллов сплава Fe-3%Si, выращенных из расплава. При комнатной температуре и при статической нагрузке деформация осуществляется через скольжение в направлении 1/2〈111〉 вдоль плоскостей, в которых составляющая напряжения скольжения максимальна. Свойства пластичности определяются движением винтовых дислокаций, которые вызывают рост полос скольжения в ширину.
