中子衍射利用中子不带电、穿透力极强、能直接鉴别核素、比X射线与电子束对轻元素灵敏、具有磁矩等特点，业已成为一种独特的从原子和分子尺度上表征各种物质的结构和微观运动的高新技术。本文着重介绍了原位中子衍射技术作为材料四维表征技术在金属材料的残余应力、变形机制、固态相变、纳米偏聚团等方面的研究进展。

Atomistic Simulation of the Orientation-dependent Plastic Deformation Mechanisms of Iron Nanopillars

Y. Zhang

材料科学技术（英文）

Tensile tests were performed on iron nanopillars oriented along [001] and [110] directions at a constant temperature of 300 K through molecular dynamics simulations with an embedded-atom interatomic potential for iron. The nanopillars were stretched until yielding to investigate the onset of their p...
