Abstract : The microstructure of titanium alloy castings is improved by a process which comprises beta-solution heat treating the cast article at or near the beta-transus temperature of the alloy, cooling the article to room temperature at a rate in excess of air cooling and aging the article at a temperature about 0.8 to 0.9 of the beta-transus.
