摘要

利用高能 X 射线衍射定量评估了在单轴拉力下通过累积轧制粘接法加工的多层钛/铌复合材料中的位错演变。...研究发现，位错的动态演变，而不仅仅是位错密度的死后分析，可以解释多层复合材料的延展性，这种延展性可以通过调整位错密度来调整。

Unraveling the origin of ductility in multilayered Ti/Nb composites: role of dislocation evolution

Dislocation evolution in multilayered Ti/Nb composites processed by accumulative roll bonding under uniaxial tension was quantitatively evaluated by high-energy X-ray diffraction. The composites wi...Dynamic evolution of dislocations, rather than only dislocation densities obtained by post-mortem analysis, is found to explain ductility of multilayered composites, which can be tailored by adjust...

期刊介绍： Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
