Abstract
The phase equilibria between titanium, Ti-β(bcc) and Ti-α(hcp), titanium aluminide, Ti₃Al-α2(hcp), and titanium silicide, Ti₅Si₃(hcp), have been investigated in the temperature range of 973 to 1473K. Binary and ternary titanium alloys containing 14 to 22 at% aluminium and 1 to 3.5 at% were produced by arc melting. The as-cast samples were then homogenized at 1573K, quenched and isothermally heat treated at temperatures between 973 and 1373K. The microstructures have been characterized by light and analytical electron microscopy, and X-ray diffractometry. Quantitative chemical analysis was carried out by analytical electron microscopy equipped with X-ray energy dispersive analysis (EDX). These results have been used to propose an experimental version of a portion of the ternary phase diagram in the temperature range of 973 to 1473K.
