Correlating microstructure recovery to rejuvenation of high-temperature creep properties in a crept single-crystal superalloy

Academic debate still exists as to whether and how multi-scale microstructure recovery is linked to creep properties rejuvenation of superalloys. We propose a rejuvenation heat treatment (RHT) for ...Special creep time and plastic deformation limit determined complete rejuvenation: the first relates to phase- and dislocation-recovery, and the latter is not fixed depending on plastic deformation...

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.
