Age-hardening behaviour of two metastable beta-titanium alloys

▶ Age-hardening responses of Ti-10V-2Ni and Ti-10V-6Cu alloys are insensitive to quench rate. ▶ β-Phase lattice stability influences the kinetics of α-precipitation. ▶ Intermetallic phase precipitated at the α/β interface tends to stabilize the microstructure of Ti-10V-6Cu alloy. ▶ Ti-10V-6Cu shows deep-hardening capability.
