Other AbstractThe microstructure evolutions of the TC16 titanium alloy corresponding to different cooling rates at 800 ℃ were investigated by techniques of XRD,SEM and TEM.The tensile properties of each sample were finally evaluated.The results show that TC16 titanium alloy consists of primary phase,α″ martensite,thermal phase and metastable phase in both water quenching and air cooling samples,but only primary α phase and metastable phase are identified in furnace cooled sample.The volume fraction and grain size of primary α phase in both water quenching and air cooling samples are nearly the same,which are smaller than that of furnace cooling one.The dual yielding phenomenon was observed on the engineering stress-strain curves of both water quenching and air cooling samples.With decreasing the cooling rate,the yield strength of TC16 titanium alloy increases.The ultimate tensile strength of water quenching and air cooling samples exhibits the same value which is larger than that of furnace cooling one.Although the slight difference on the tensile strength for three kinds of samples,the elongation and area reduction representing the ductility are nearly the same.
