In relation to the problem of determining reliable values of mechanical characteristics of metallic materials at temperatures below 30 K, the peculiarities of repeated neck fomation have been studied on cylindrical specimens of structural alloys for cryogenic engineering in the case of occurrence of the effect of low-temperature discontinuous yield. The evaluation performed of the rigidity and inhomogeneity...
The regularities of repeated necking have been studies on flat specimens of alloys for cryogenic engineering in the case of effect of low-temperature discontinuous yield. It has been shown that in contrast to cylindrical specimens, in this particular case there is a considerable deviation of the stressed state from linear stress, which affects greatly the mechanical characteristics determined and...
