    摘要： Disclosed are Ti-Al alloys having increased ductility and Ti-Al alloys having increased ductility and lowered melting points, in both of which the main constituent phase is an intermetallic compound, TiAl.The Ti-Al alloys having increased ductility essentially consisting of Al: 28-38%, and B: 0.005-0.3%, the balance being Ti and inevitable impurities.Since the alloys of this type have good processability, they are suitable as materials for mechanical parts of rotating or reciprocating systems, where high heat-resistance and high specific strength are required.The Ti-Al alloys having increased ductility as well as lowered melting points essentially consisting of Al: 28-38%, one or two of Ni: 0.05-3.0% and Si: 0.05-3.0%, and the balance being Ti and inevitable impurities. Optionally, this alloy further contains B: 0.005-0.3%.The alloy of this type is, in addition to the above use, suitable for producing machine parts made by precision casting technology.
