真空钎焊TiAl基合金用Ti-Zr-Cu-Ni-Co-Mo钎料的钎焊性能（英文）
|
摘要
采用非晶和晶态Ti-25Zr-12.5Cu-12.5Ni-3.0Co-2.0Mo(质量分数,%)钎料对Ti-47Al-2Nb-2Cr-0.15B(摩尔分数,%)合金进行真空钎焊连接,对两种钎料的熔化行为、润湿铺展性、填缝隙能力以及由钎焊TiAl基合金所得的钎焊接头进行详细的研究。结果表明:与晶态钎料相比,非晶钎料具有更窄的熔化温度区间、更低的液相线温度和熔化激活能;同时,非晶钎料在Ti-47Al-2Nb-2Cr-0.15B合金表面上具有更优异的钎焊性。非晶和晶态两种钎料的钎焊接头均由两侧的界面反应层和中心钎焊层组成,非晶钎料钎焊接头的抗拉强度均高于相同钎焊工艺参数下的晶态钎料钎焊接头的抗拉强度,且在钎焊温度1273K下获得的钎焊接头的抗拉强度达到最大值254 MPa。
Ti-47Al-2Nb-2Cr-0.15B(mole fraction, %) alloy was vacuum brazed with amorphous and crystalline Ti-25Zr-12.5Cu-12.5Ni-3.0Co-2.0Mo(mass fraction, %) filler alloys, and the melting, spreading and gap filling behaviors of the amorphous and crystalline filler alloys as well as the joints brazed with them were investigated in details. Results showed that the amorphous filler alloy possessed narrower melting temperature interval, lower liquidus temperature and melting active energy compared with the crystalline filler alloy, and it also exhibited better brazeability on the surface of the Ti-47Al-2Nb-2Cr-0.15B alloy. The TiAl joints brazed with crystalline and amorphous filler alloys were composed of two interfacial reaction layers and a central brazed layer. Under the same conditions, the tensile strength of the joint brazed with the amorphous filler alloy was always higher than that with the crystalline filler alloy. The maxmium tensile strength of the joint brazed at 1273 K with the amorphous filler alloy reached 254 MPa.
