Abstract

ABSTRACT Directional recrystallisation processing is a solid-state process in which a specimen traverses a sharp hot zone and one or a few grains grow as they pass through the hot zone. The mechanism can be either a primary recrystallisation or secondary recrystallisation process, or a combination of both. The mechanism can be either primary recrystallisation or secondary recrystallisation process, or a combination of both. Directional recrystallisation was invented more than 80 years ago to achieve columnar grain structures or single crystals that have enhanced mechanical properties. This review discusses the effects of both processing parameters, including the temperature gradient, hot-zone velocity, and annealing temperature, and microstructural parameters, including stored energy, grain size, initial texture, solutes, and both soluble and insoluble particles, on the resulting microstructures. The results of simulations of directional recrystallisation, including Monte Carlo simulations, Front-Tracking methods, and phase-field simulations, are also reviewed. Finally, the effects of directional recrystallisation on material properties are discussed.

定向再结晶工艺综述

摘要定向再结晶工艺是一种固态工艺，试样穿过一个尖锐的热区，一个或几个晶粒在穿过热区时生长。该机制可以是一次再结晶或二次再结晶过程，也可以是二者的组合。其机制可以是一次再结晶或二次再结晶过程，也可以是二者的结合。定向再结晶是80多年前发明的，目的是获得具有增强机械性能的柱状晶粒结构或单晶。这篇综述讨论了两个工艺参数（包括温度梯度、热区速度和退火温度）和微观结构参数（包括储能、晶粒尺寸、初始织构、溶质以及可溶性和不溶性颗粒）对所得微观结构的影响。还回顾了定向再结晶的模拟结果，包括蒙特卡罗模拟、前沿跟踪方法和相场模拟。最后，讨论了定向再结晶对材料性能的影响。
