    摘要:

    利用Gleeble 3500熱模擬試驗機在添加和未添加擴散連接中間層條件下對Zr41.25Ti13.75Cu12.5Ni10Be22.5塊體非晶合金與純銅的擴散連接性進行了研究。實驗結(jié)果表明，在兩種條件下均獲得了無裂紋和空洞的良好的連接界面。通過掃描能譜分析和電子探針分析在連接界面處觀察到明顯的元素擴散，但元素擴散距離較窄。非晶合金中晶化相的出現(xiàn)促進了界面處元素的擴散。

    Abstract:

    The diffusion bonding capability between Zr41.25Ti13.75Cu12.5Ni10Be22.5 bulk metallic glass and pure Cu with and without interlayer was studied on a Gleeble3500 thermomechanical simulator. Good diffusion bonding joints without cracks and voids have been obtained under both conditions. Atomic diffusion at the interface was obviously observed using EDS and EPMA methods, while the diffusion zones were very narrow. The crystalline phases which were transformed from amorphous state accelerated the atomic diffusion at the interface.
