摘要: 通過研究不同溫度時熱等靜壓(HIP)多元擴散偶DD402/FGH95中的A1,Ta和Ti元素的擴散規律,發現DD402單晶中存在A1和Ta元素的上坡擴散.因此單晶中在近結合界面處形成了A1,Ta和Ti元素的富集區以及γ'相的筏形化.對A1和Ta元素的擴散流量及擴散深度進行計算.計算結果與試驗結果相吻合.

Abstract: Regularities of interdiffusion of Al, Ti and Ta for DD402/FGH95 couple during HIP at different temperatures were studied. The up-hill diffusion flux of Al and Ta in single crystal DD402 was found. As a result, a rich zone of γ'phase forming elements and rafted γ'phase were developed in single crystal DD402 close to the bonded interface. The diffusion fluxes and diffusion depths of Al and Ta were calculated. The calculated results were corresponding to those the experiments.
