    摘要:

    用座滴法研究了高真空下Zr41.25Tin13.75Ni10Cu12.5Be22.5（原子百分?jǐn)?shù)，下同）熔體在W上的潤濕行為及界面相互作用，并用浸滲法制備了W絲增強的Zr41．25Ti13．75Ni10Cu12.5Be22.5塊狀非晶復(fù)合材料。結(jié)果表明：在1053K～1173K之間，Zr41.25Ti13.75Ni10Cu12.5Be22.5熔體與W具有較好的潤濕性。潤濕溫度升高會顯著降低平衡接觸角，并加速熔體的鋪展，但也會增大W的溶解量。繼續(xù)升高溫度對平衡接觸角和達(dá)到平衡接觸角所需時間的影響很小。好的潤濕性和快的鋪展速率為制備W絲增強的Zr41.25Ti13.75Ni10Cu12.5Be22.5塊狀非晶復(fù)合材料選擇合理的工藝參數(shù)提供了較大的自由空間。

    Abstract:

    The wetting behavior and interracial interaction of Zr41 25Ti13.75Ni10Cu12. 5Be22. 5 molten on W were studied by the sessile drop method in high vacuum. Tungsten fiber reinforced Zr41.25Ti13.75Ni10Cu12.5Be22.5 bulk metallic glass matrix composite was fabricated by infiltration process. The results show that there is a good wettability in Zr41.25Ti13 .75Ni10Cu12.5Be22. 5 molten/W wetting system between 1053 K and 1173 K. Increase of wetting temperature resulted in the decrease of equilibrium contact angle and the increase of spreading rate and solution of W. It had little effects on the equilibrium contact angle and the equilibrium wetting time when increasing above 1173 K. Good wettability and rapid spread rate provided a wide operating space for fabricating tungsten fiber reinforced Zr41.25Ti13 75Ni10Cu12.5Be22. 5 bulk metallic glass matrix composite.
