摘要：
The equal-channel angular pressed (ECAPed) 6061 Al alloys processed with various pre- and post-ECAP heat treatments were compared in terms of the balance between strength and tensile ductility, and it was concluded that the post-ECAP low-temperature aging treatment was most effective in improving the strength whilst retaining a moderate level of tensile ductility.
