摘要

在2273 K温度下退火的等原子铌钽钨bcc中熵合金的扩展X射线吸收精细结构（EXAFS）显示出出乎意料的小的第1壳和第2壳元素特异...在2273 K温度下退火的中熵铌钽钨bcc合金仍然显示出短程有序的迹象，这与其在较低温度下的偏析行为有关，证实了对fcc合金的观察结果。

Local lattice distortions and chemical short-range order in MoNbTaW

Extended X-ray absorption fine structure (EXAFS) conducted on an equiatomic MoNbTaW bcc medium-entropy alloy that was annealed at 2273 K reveals unexpectedly small 1st and 2nd shell element-specifi...A medium-entropy MoNbTaW bcc alloy annealed at 2273 K shows still signs of short-range ordering which relate to its segregational behavior at lower temperatures, corroborating observations on fcc a...

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.
