Abstract As a type of cooperative deformation like twinning, kinking can improve the deformability of materials by stress relaxation and crystal reorientation. In this work, kinking with 〈0 1 1〉 lattice rotation axis was identified in a refractory TiZrHfNb0.7 medium-entropy alloy (MEA). Through intragranular misorientation axis (IGMA) analysis, the {1 1 2} 〈1 1 1〉 dislocation slip was determined. The formation of intensive band structure in 70% cold rolled alloy was attributed to continuous nucleation and propagation of kink bands in coarse grains.

耐火 TiZrHfNb0.7 中熵合金中的扭结

摘要 作为孪生等协同变形的一种，扭结可以通过应力松弛和晶体重新取向来提高材料的变形能力。在这项工作中，在难熔的 TiZrHfNb0.7 中熵合金 (MEA) 中发现了具有〈0 1 1〉晶格旋转轴的扭结。通过晶内取向轴（IGMA）分析，确定了{1 1 2} 〈1 1 1〉位错滑移。70%冷轧合金中密集带结构的形成归因于粗晶中扭结带的连续形核和扩展。
