摘要: Abstract In this paper, an analytical model of ECAP process with eccentric unbonded bimetal rod is proposed by slab method. Based on the discussion, effects eccentricity ratio and diameter inner as well geometrical parameters mold bonding are obtained. Also first time that different material arrangements both taken into consideration in ECAP. Two kinds rods researched, when outer pipe hard core soft, will be relieved. When soft hard, enlarged. These changes can more than 10% some situations. order to verify these conclusions, experiments aluminum copper designed conducted. experiments, 3 molds 10 ratios 5 diameters discussed two The measured results agreement those calculated model. Most errors between measurements calculations less 6%.
