Owing to the barreling, the theoretical model on the basis of Hill s general method is used to calculate the flow stress of a cylindrical specimen under uniaxial simple compression so as to consider the friction effect at the die-specimen interface. A method of evaluating the friction coeffcient by combining compression tests with the finite element method is presented. The real flow behavior of AA6063 aluminium alloy can be described with sinh-Arrhenius equation. The hot deformation activation energy Q derived from the corrected stress and strain data is 232.350 kJ/mol. 关键词：铝合金压缩测试摩擦应力激活能量
