- (1)
- The solution-strengthening effects of Mo were found to be larger than Al in the α phase. It was also found that the solution-strengthening of Al in the α phase demonstrated a parabolic trend, which meant that the solution-strengthening effects were apparent when the composition of Al was less, while the solution-strengthening effects weakened when the composition of Al in the α phase increased.
- (2)
- The hardness of the titanium alloy was found to be determined by both the solution-strengthening and precipitation-strengthening of α.
