Abstract

The crystallographic orientations and residual stresses within recrystallizing grains in partially recrystallized β titanium—Gum Metal—were examined non-destructively in 3D using synchrotron Differential Aperture X-ray Microscopy. Contrary to common assumptions, significant local stresses and stress variations are observed within the recrystallizing grains. The results reveal that the development of these local residual stresses depends on the plastic deformation mode and material’s elastic constants, rather than grain properties such as size and orientation, or even the material’s yield stress. This work provides insights valuable for the design of advanced materials with heterogeneous microstructures. GRAPHICAL ABSTRACT

部分再结晶胶金属生长晶粒中残余应力的三维映射

利用同步辐射差孔径x射线显微镜对部分再结晶β钛胶金属的结晶取向和再结晶晶粒内的残余应力进行了三维无损检测。与通常的假设相反，在再结晶晶粒中观察到显著的局部应力和应力变化。结果表明，这些局部残余应力的发展取决于塑性变形模式和材料的弹性常数，而不是晶粒尺寸和取向等晶粒性能，甚至不是材料的屈服应力。这项工作为设计具有异质微结构的先进材料提供了有价值的见解。

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.
