摘要:
马氏体相变作为一类重要的结构转变而广泛存在于形状记忆合金、钢铁等智能以及工程材料中。从原子尺度去理解马氏体相变的微观响应机制对于开发和提高这类材料的性能至关重要。本文主要综述了利用分子动力学的手段研究马氏体相变的相关工作：首先本文介绍了形状记忆合金中的马氏体相变行为及其尺寸效应方面的研究进展；进而讲述了结构金属材料中的马氏体相变行为，特别是极端压缩变形条件下马氏体相变与塑性变形的交互作用机制。最后简述了目前相变模拟中存在的问题以及未来的展望。
Abstract:
Martensitic transformation (MT) is one of the most commonly encountered transformations, existing in many engineering materials, such as steel and shape memory alloys. Optimizing the performance of these transforming materials requires a fundamental understanding the physical processes of MT from the atom-level. In the absence of experimental information, numerical simulations are critical to the study of the transformation behaviors at their characteristic lattice length scales. This review summarized recent atomic simulation works on martensitic materials. The MT behaviors in shape memory alloys as well as their size effect are first discussed. Then, we analyze the phase transformation in structural metals, especially their interaction with plastic deformations under extreme compression. Finally, the existing problems and prospects of the related research are presented.
