Yield Strength Phenomenon in Ti-6Al-4V

reportActive / Technical Report | Accession Number: ADA040931 | Open PDF

Abstract:

The titanium alloy Ti-6Al-4V has a very low yield strength LYS when water quenched from 850 C. This LYS is often attributed to the deformation- induced transformation of retained beta to martensite. This report gives evidence that it is not accurate to postulate a TRIP transformation-induced plasticity type of mechanism to explain the LYS in the 6-4 alloy.
