Abstract

A distinctive combustion phenomenon is revealed by promoted ignition combustion tests of Ti-25V-15Cr and Ti-6Al-4V alloys. The relationship between ignition temperatures and oxygen pressures obeys the Van't Hoff equation. The ignition temperatures of Ti-25V-15Cr are higher than that of Ti-6Al-4V due to the decomposition and volatilization of V₂O₅. However, the burning velocity of Ti-25V-15Cr is faster than that of Ti-6Al-4V, attributed to the different migration way of solid-liquid interface. The phase structure of the matrix is considered as the key factor that controls the spreading rate of the solid-liquid interface and the burning velocities of Ti-25V-15Cr and Ti-6Al-4V alloys.
