摘要
Tensile properties dependence of elevated testing temperatures (100 degrees C similar to 450 degrees C) on as extruded and as friction stir processed Al-Cu 2218 alloy were investigated. The tensile deformation resistance of an as friction stir processed sample is higher than an as extruded one as increased testing temperature up to 300 degrees C and this is a consequence of natural aging effect. However, the tensile deformation resistance decreased evidently as the testing temperature raised to 400 degrees C similar to 450 degrees C, meanwhile there was a concomitant improvement of tensile ductility due to a homogeneously grain refinement which facilitated a pronounced grain boundary sliding in this temperature range.
