- 論文の詳細を見る
Al-Cu-Mg series A2017 alloy has been diffusion-welded to titanium in the range of temperature at which the liquid and solid phases coexist in the A2017 alloy, in order to investigate effects of the coexisting liquid phase on the bond strength. The tensile strength of the joint increased remarkably with increasing the liquid phase and took a maximum value (*240MPa) when the volume fraction of the liquid phase was 6〜7% (welding temperature*858K). However, the maximum strength of the joint was considerably lower than those of the base metals of A2017 alloy and titanium. The maximum strength is considered to be determined by the strength of the intermetallic compound layer forming in the titanium adjacent to the bond interface ; for the joint fractured at the intermetallic compound layer on tensile test. The intermetallic compound layer consisted of Al_3 Ti and a compound containing copper.
