TC4钛合金冷却过程中组织变化分析
The microstructural evolution of TC4 alloy during cooling from the solution temperature
摘要
Abstract
The microstructural evolution of TC4 alloy during cooling from the solution temperature was in-vestigated by using an optical microscopy,a scanning electron microscopy and a Vickers hardness analyzer. The results have shown that the main phase transformation was β→α during cooling. Thickness of α lath in-creased with decreasing cooling rates. The hardnesses of the specimens which were cooled from 850 ~ 800 ℃after solid solution at 1 000 ℃ reached maximum value due to a uniformly fine-grained structure of α-phase. The hardnesses of the specimens decreased with decreasing cooling temperature. The hardness changes of the specimens are also most likely related to the precipitation of Ti2 AlV(O)and Ti2 AlV phases during cooling.关键词
