The dynamics of deformation bands at the prefracture stage of the aluminum-magnesium alloy 5556 has been examined using the high-speed video recording. It has been revealed that, in the artificially aged and recrystallized alloys, the correlations between the propagating deformation bands and the development of the main crack are of different character.  相似文献

The phase composition inside and outside of impressions formed under indentation of silicon in the presence of low-intensity beta radiation is studied. Comparative analysis of obtained spectra makes it possible to conclude that the contribution of phase transformations under indenter during W-shaped variation of silicon microhardness induced by beta radiation is insignificant. Consequently, nonmonotonic silicon softening is caused by the transformation of the point defect (intrinsic and radiation-induced) subsystem in conditions of low dislocation mobility at room temperature.  相似文献
