Time-Dependent Plastic Flow in Metals and Alloys (Materials Research)

采用计算机模拟和实验相结合的方法对纯金属和金属间化合物镍铝化物(Ni3Al)进行了随时间变化的研究。这项研究将包括根据单个位错的弹性性质研究变形过程中形成的晶胞结构，并开发塑性流动的本构模型，包括流动动力学、应变硬化、静态和动态恢复。这项工作的总体目标是开发一个能够描述低温和高温变形的基本特征的模型。

An investigation of time-dependent deformation employing both computer modelling and experiments will be conducted on pure metals and the intermetallic compound, nickel aluminide (Ni 3AL). The research will include studies of the cell structures developed during deformation in terms of the elastic properties of individual dislocations and the development of a constitutive model for plastic flow, including flow kinetics, strain hardening, static and dynamic recovery. The overall aim of this work is to develop a model which is capable of describing the basic characteristics of both low and high temperature deformation.
