Abstract
A study on the phase transformation of martensite in metastable beta phases induced by sub-zero quenching after solid solution treatment has been done. TEM examination was carried out to characterize the structure of martensite and metastable phase in a commercial titanium alloy, β-C. The results showed that the martensite had a twinned hcp structure. It is believed that this structure is generated initially by a martensitic transformation from the metastable bcc phase which is consisted of tweed structure in matrix.
