在[001]取向的Fe-30%Cr合金单晶中观察到了伴随46%应变带的特殊形变。在473K时效30min后，试件再次变形。在23.5%的菌株。第二个Luders乐队从卡盘的另一边开始。通过对试件侧面的表面观察，确定了带内的传播速度、宽度和应变率。该带内的移动位错密度约为2×108 cm/cm~3。确定了变形过程中的有效应力和内应力，分析了变形机理。
Peculiar deformation accompanied by band having 46% strain was observed in the [001] oriented Fe-30%Cr alloy single crystal. Specimen was again deformed after ageing at 473K for 30min. at the 23.5% strain. Second Luders band started from the opposite side of the chuck. From the surface observation of the side surface of the specimen, the propagation speed, width and the strain rate in the band were determined. The mobile dislocation density in the band was also estimated to be about 2×108cm/cm3. The effective and internal stress were determined during the straining in order to analyze the mechanism of deformation.
