    摘要:

    采用電弧熔煉和快冷甩帶工藝制備了(Ti0.46Cu0.14Zr0.27Ni0.13)1-xSix非晶釬料,研究了添加一定量的Si對(duì)釬料非晶形成能力的影響。結(jié)果表明,當(dāng)Si的含量達(dá)到0.5%時(shí)釬料的非晶形成能力最強(qiáng),釬料的潤(rùn)濕面積為3.06 cm2,過(guò)冷液相區(qū)寬度(?Tx)?Tx=56 ℃,約化玻璃轉(zhuǎn)變溫度(Trg)Trg=0.5387,液相線溫度為949 ℃。以此非晶合金作為釬料對(duì)SiC和TC4進(jìn)行真空釬焊,所得釬焊接頭剪切強(qiáng)度為80 MPa。Si元素的加入顯著提高了釬料的非晶形成能力。

    Abstract:

    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.
