摘要

在具有易滑动取向的Cu-15% Al-2% Co (at %)非相干煤颗粒的非均相合金单晶中，塑性变形是通过机械孪晶实现的，并研究了这种依赖关系。在77 K时，卸载时发现与弹性孪晶相关的异常大的可逆变形(e≈2.5%)(超弹性)。研究了超弹性效应与颗粒分散度、测试温度和晶体轴向的关系。[忽略俄语文本]。

Superelasticity Effects in Single Crystals of Cu-15% Al-2% Co with Non-Coherent Particles Due to Twinning

In single crystals of an easy-glide orientation of the heterogeneous alloys Cu-15% Al-2% Co (at %) with non-coherent particles of CoAl the plastic deformation is shown to be realised by means of mechanical twinning and the dependence is investigated. At 77 K abnormally large reversible deformation (e ≈ 2.5%) (superelasticity) associated with elastic twinning is found on unloading. The dependence of superelasticity effects on the particle dispersion, the test temperature, and crystal axis orientation is studied. [Russian Text Ignored].
