| Abstract | ||
| Iron alloying element addition to pure titanium can be used to enhance strengthening as well as β-phase stabilizer. However, the outcome depends on the processing route to some extent. Mechanical alloy technique is adapted in this work to produce titanium alloys with 7wt% iron content and 1wt% Aluminum. The obtained nano-size particles have two phases α and β structures and the formation of the second β-phase is mainly enhanced by the milling force. Heating the produced grain compacted powder to a temperature above the beta phase transus temperature followed by quenching to ambient temperature resulted in α-martensite partial transformation. This result can indicate that the obtained β-phase for the present alloys is not fully stabilized by the iron additions. | ||
