Abstract : By analogy with TRIP steels, which attain high strength combined with high tensile elongation, it should be possible to devise a titanium alloy where beta phase is retained such that martensitic start < or = room temperature < or = martensitic decomposition and martensitic transformation occurs during deformation. If this condition can be achieved in a highly strengthened retained beta, it is possible that, for a given yield strength, the alloy could exhibit enhanced tensile elongation and fracture toughness. This report summarizes experimental results of the first year of a program for development of a TRIP-type titanium alloy. (Author)
