Abstract：Water cooling temperature affects morphologies and mechanical properties of TC4 alloy. TC4 alloy was
water cooled from 3 different temperatures after solution treating. The results show that the original β-grain and α-phase
were observed when the specimens were water cooled at 900℃ after solid solution. A uniformly fine-grained structure of
α-phase was observed when the specimens were water cooled at 700℃. The tensile strength and hardness of specimens exhibited
the maximum value (867MPa and HV5218), respectively. More α-phases were precipitated from β-phases with decreasing
water cooling temperature. The tensile strength and hardnesses of the specimens decreased due to coarse lamellar
α-phase.
