Recovery facilitated by interphase boundary motion circumvents recrystallization in superalloy single crystals

Dislocation recovery lowering the driving force for recrystallization would be able to suppress the latter in Ni-based superalloy single crystals, but was believed unlikely due to their low stackin...In γ/γ′ two-phase Ni-based superalloy single crystals, dislocation recovery is achieved via an interphase-boundary motion enabled mechanism, defying the traditional wisdom of dislocation climb/cros...

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.
