摘要：
A method for improving the microstructure of an article made by powder metallurgy of blended elemental titanium powder which comprises beta-solution heat treating the article at a temperature approximately equal to the beta-transus of the equivalent alloy, rapidly cooling the article, annealing the article at a temperature about 10 to 20% below the beta-transus and air cooling to room temperature. The resulting article has a fine alpha plate structure in a matrix of discontinuous beta phase.
