Analysis of thermal behavior during equal channel multi-angular pressing by the 3-dimensional finite volume method

Abstract

Thermal behavior and heat transfer during equal channel multi-angular pressing process of AZ31 alloy at room temperature were analyzed by using the 3-dimensional finite volume method. The simulations were carried out at different frictional conditions (friction factor m = 0, 0.1 and 0.2), pressing speeds (v = 2 and 20 mm/s), and pressing routes (A, B and C). The pressing speed influences more on the temperature rise of the AZ31 sample than the pressing route and friction condition. The initial temperature 293 K of the AZ31 alloy was increased up to 395 K for 20 mm/s pressing speed during the pressing. (c) 2008 Elsevier B.V. All rights reserved.
