Effect of post-deposition heat treatment on laser-TIG hybrid additive manufactured Al-Cu alloy

Effect of post-deposition heat treatment on laser-TIG hybrid additive manufactured Al-Cu alloy

After solution + artificial aging treatment (T6 heat treatment) of 2219 aluminum alloy fabricated by laser-tungsten inert gas (TIG) hybrid method, more interestingly, we found that both the strength and elongation were improved. The strengthening mechanism has been analysed in details. Results showe...
