Abstract

The precipitation of grain boundary (GB) κ-carbides critically influences the damage-tolerance ability of high-Mn high-Al lightweight steels, particularly in harsh environments (cryogenic and H env...We originally report that grain boundary κ-carbides can result from spinodal decomposition rather than conventional heterogeneous nucleation and refute the possibility of avoiding their precipitati...

奥氏体高锰轻钢中晶界κ-碳化物的形成与生长

晶界(GB) κ-碳化物的析出严重影响高锰高铝轻钢的损伤容忍能力，特别是在恶劣环境(低温和高温环境)中。我们最初报道了晶界碳化物可能是由独立分解而不是传统的非均相成核产生的，并反驳了避免其析出的可能性。

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.
