摘要: 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 carried out different frictional conditions (friction factor m = 0, 0.1 0.2), speeds (v = 2 20 mm/s), routes (A, B C). speed influences more on rise sample than route friction condition. initial 293 K was increased up to 395 K for 20 mm/s pressing.
