摘要: Equal channel angular pressing is an outstanding method for imposing large plastic deformation to metallic materials without any decreasing in cross section area of as processed samples. In this paper, the effect working temperature, ram speed and number passes on formation adiabatic shear bands Al6061 during equal was investigated. Billets alloy were up four via route BC from room temperature 200oC with two speeds using a die that imparts effective strain ~1.1 per pass. The results have demonstrated onset banding strongly depends speed: more frequently observed at higher than lower speed. Although geometry macroscopic view band similar all cases, development well processing temperature.
