Abstract
Ti40 alloy (Ti-25V-15Cr-0.2Si) is a highly stabilized beta-titanium alloy w ith good burn resistance. Its microstructures were examined and analyzed by OM, SEM, TEM, XRD and EDX. The results reveal that Ti40 is a single beta-p hase alloy. There are quad-point boundaries and a white zone around the gra in boundaries in the as-cast structures, leading to difficulties in ingot b reakdown. The recrystallization finishing temperature is 820 degrees C, and the second recrystallization is at 1100 degrees C. The subgrains emerge if solution treatment temperature is greater than 910 degrees C and aging at 600 degrees C, which leads to a good combination among emerge tensile prope rties.
