抄録

Structures of Ti–Al–V alloys have been examined by means of electron probe microanalysis and X-ray diffractometry after being annealed for 2.68 Ms at 1073 K or for 691 ks at 1273 K.<BR>Two three-phase equilibriums, Al₈V₅+(V, Ti)Al₃+(V) and Ti₃Al+(β−Ti)+TiAl, have been found, and isothermal diagrams at 1073 K and 1273 K have been reconstructed.<BR>The titanium content in Al₈V₅ phase is about 5 mass% at 1273 K and 1 mass% at 1073 K. In the TiAl compound which contains vanadium up to the solubility limit, the axial ratio c/a varies from 1.012 to 1.050 with increasing aluminium content.
