摘要

微孪晶是γ′沉淀强化镍基超合金在中温服役期间的一种重要机理。这项研究首次解释了为什么微孪晶表现出取向依赖性和拉伸-压缩不对称，而堆叠断层却没有，尽管它们都源于γ′淀......这项研究首次解释了为什么微孪晶表现出取向依赖性和拉伸-压缩不对称，而堆叠断层却没有，尽管它们都源于γ′淀...

Microtwinning mechanism revealed by its orientation dependence and tension-compression asymmetry in γ′ precipitate-strengthened Ni-based superalloys

Microtwinning is observed as an important mechanism in γ′ precipitate-strengthened Ni-based superalloys during service at intermediate temperatures. Here, the effect of crystal orientation and stre...For the first time, this work explains why microtwinning exhibits orientation dependence and tension-compression asymmetry while stacking faults do not, although they both originate from the activi...

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.
