摘要

一般来说，钛和钛合金的变形主要由位错和变形孪晶引起。在这项工作中，在全薄片 Ti-6Al-4V 合金中观察到了一种新的变形带 (DB)。...首次观察到扭结带的存在，并揭示了在 α+β Ti 合金中扭结带诱导的 β 到 α 相变机制。

Kink band induced β→α phase transformation in lamellar α+β Ti alloys

Generally, deformation in Ti and Ti alloys are dominated by dislocations and deformation twins. In this work, a novel deformation band (DB) has been observed in the fully lamellar Ti-6Al-4V alloy. ...First observing the existence of kink band and unveiling the kink band induced β to α phase transformation mechanism in α+β Ti alloys.

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.
