Effects of Water Cooling Temperature on the Microstructural Evolution of TC4 Alloy
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.
