弹性应力对微结构不稳定性的影响

Elastic stress effects on microstructural instabilities

M P Gururajan, Arka Lahiri

摘要:

本文综述了弹性应力对微结构不稳定性影响的相场模拟研究。我们将主要关注四种弹性应力驱动的不稳定性:(i)Spinodal相分离;(ii)粒子分裂;(iii)Rafting;和(iv)Asaro-Tiller-Grinfeld(ATG)不稳定性。本文综述如下:在第1节中,我们简要介绍了一些重要的和有趣的实验观察弹性应力对微观结构不稳定性的影响;在第2节中,我们描述了合理的细节,在理解弹性应力对固体微观结构不稳定性的影响的理论发展。第1节和第2节既不全面也不完整;然而,它们有助于为第3节讨论的相场建模研究奠定基础(并提供观点)。在第4节中,我们总结并指出未来的发展方向。

英文摘要:

This review is on the phase field modelling studies in elastic stress effects on microstructural instabilities. We will focus primarily on four elastic stress driven instabilities: (i) Spinodal phase separation; (ii) Particle splitting; (iii) Rafting; and, (iv) Asaro-Tiller-Grinfeld (ATG) instabilities. This review is organised as follows: in Section 1, we briefly describe some of the important and interesting experimental observations on elastic stress effects on microstructural instabilities; in Section 2, we describe, in reasonable detail, the theoretical developments in understanding the effects of elastic stress on microstructural instabilities in solids. Both Section 1 and 2 are neither comprehensive nor complete; however, they are helpful in setting the stage for discussion of (and, in giving a perspective on) phase field modelling studies that will be discussed in Section 3. In Section 4, we conclude with a summary and indication of future directions.
