Abstract
Abstract
The effect of strain path change on deformation and recrystallization behaviour of Al-Mg alloy was investigated. Solutionized samples were subjected to uni-directional rolling and multi-step cross rolling at cryogenic temperature to yield distinct deformation texture and microstructure. Rolled samples were then annealed at different temperatures (523–573 K) for one hour to obtain partially and fully recrystallized microstructure. It was observed that, change in strain path plays a key role in controlling both deformation texture and microstructure and recrystallization texture and microstructure. This was manifested in terms of a copper type texture for the unidirectionally rolled sample and strong brass and rotated brass component for the multi-step cross rolled sample. Upon subsequent annealing, it was observed that the extent of recrystallization in Al-Mg alloy depends on the initial deformation texture and microstructure, with the cross-rolled sample showing sluggish recrystallization kinetics compared to unidirectionally rolled samples.
