中文摘要:
      采用电弧熔炼和快冷甩带工艺制备了(Ti0.46Cu0.14Zr0.27Ni0.13)1-xSix非晶钎料,研究了添加一定量的Si对钎料非晶形成能力的影响。结果表明,当Si的含量达到0.5%时钎料的非晶形成能力最强,钎料的润湿面积为3.06 cm2,过冷液相区宽度(?Tx)?Tx=56 ℃,约化玻璃转变温度(Trg)Trg=0.5387,液相线温度为949 ℃。以此非晶合金作为钎料对SiC和TC4进行真空钎焊,所得钎焊接头剪切强度为80 MPa。Si元素的加入显著提高了钎料的非晶形成能力。

英文摘要:
      The (Ti0.46Cu0.14Zr0.27Ni0.13)1-xSix amorphous filler metal was prepared by arc melting and fast-cooling melt-spinning technologies, and the effect of a certain amount of Si added to the filler metal on its amorphous forming ability was studied. The results show that the filler metal presented the strongest amorphous forming ability when the additive Si reached 0.5%; its wetting area was 3.06 cm2,its supercooled liquid phase region width (?Tx) ?Tx=56 ℃,its reduced glass transition temperature (Trg) Trg=0.5387, and its liquidus temperature was 949 ℃. The vacuum brazing was done for SiC and TC4 using this amorphous alloy as the filler metal, and the shear strength of brazed joint was 80 MPa. The amorphous forming ability of filler metal was improved with addition of Si to the filler metal.
