摘要
An aluminum-titanium alloy and a process of making it, the alloy consistingssentially of aluminum, 4-6 wt. % titanium, 1-2 wt. % carbon, and 0.1-0.2 wt % oxygen. The alloy is an aluminum matrix supersaturated with titanium, and having throughout a fine, homogeneous dispersion of Al. sub.3 Ti particles. It is fine grained and has grain boundary dispersoids of carbides and oxides, predominantly of aluminum. An aluminum-titanium melt is rapidly solidified and then mechanically alloyed in the presence of a carbon-bearing agent. The resulting powder is degassed and hot consolidated to form articles which exhibit high strength, ductility, and creep resistance at temperatures greater than 200° C.
