Abstract
The finite element numerical simulation of hot compression deformation process of B93 aluminium alloy was carried out by DEFORM-3D software. Besides, the microstructure characteristics of deformed specimens in different regions and the relationship between non-uniform strain and dynamic recrystallisation during deformation were analysed by experimental study. The results show that the hot compression process of B93 aluminium alloy obviously exhibits a nonuniform characteristic of deformation, the region with the largest equivalent strain is the most prone to deformation. Also, in the largest equivalent strain zone, dynamic recrystallisation reacts the most complete, and the grain size reaches the minimum value. Nonuniform deformation show a rising tendency with the increase of strain rate and deformation temperature, and the influence of strain rate on nonuniform deformation is slightly greater than that of deformation temperature. The most suitable hot working process for the alloy is 410~430°C/0.001~0.01s-1.
期刊介绍:
IJCMSSE is a refereed international journal that aims to provide a blend of theoretical and applied study of computational materials science and surface engineering. The scope of IJCMSSE original scientific papers that describe computer methods of modelling, simulation, and prediction for designing materials and structures at all length scales. The Editors-in-Chief of IJCMSSE encourage the submission of fundamental and interdisciplinary contributions on materials science and engineering, surface engineering and computational methods of modelling, simulation, and prediction. Papers published in IJCMSSE involve the solution of current problems, in which it is necessary to apply computational materials science and surface engineering methods for solving relevant engineering problems.
