Abstract

The function of severe plastic deformation (SPD) rate during equal-channel angular pressing (ECAP) on the thermal and mechanical characteristics of the aluminum alloy 6030 are experimentally investigated. ECAP was carried out at room temperature onto refining grain size for Al- 6030 of square cross-section specimens.  The tests show that, for decreasing the rate of strain from 0.016 to 0.0023 s-1, the improvement in the hardness increases gradually until the highest value is reached at the rate of strain 0.004 s-1and decreases after that gradually. The percentage improvement in the hardness is around 68 % at the rate of strain 0.004 s-1. The ECAP process improves the yield strength of aluminum alloy 6030 by 222 % on average at the rate of strain 0.004 s-1. Also, for decreasing the rate of strain from 0.016 to 0.0023 s-1 the thermal conductivity increases gradually to the maximum value 137.5 W/m° K at rate of strain 0.004 s-1and decrease after that gradually. The ECAP process improves the thermal conductivity by 4.88 % for the rate of strain 0.004 s-1 as compared to the case without ECAP process. From the present experimental results, the optimum rate of strain is 0.004 s-1 to obtain the optimal thermal and mechanical properties of the aluminum alloy 6030 during the ECAP processing.
