Development of Ultrahigh-Strength, Ductile Titanium Alloys by Thermomechanical Processing and Transformation-Induced Plasticity.
Abstract
The report summarizes results of the second year of a program for development of TRIP-type titanium alloys. Ternary, quaternary, and more complex alloys were investigated for strain-or stress-induced martensitic transformation during tensile testing at room temperature. It was determined that molybdenum- and vanadium-stabilized beta alloys do not transform martensitically during deformation. Microstructural features that looked like martensite were actually mechanical twins in the beta phase. Moreover, the stress to initiate twinning is low, thus causing premature yielding and anomalously low yield strengths. (Author)
