摘要
采用金相法测定了Ti-6554钛合金的TTT曲线。结果表明:测得等温转变的"鼻温"在540℃左右,在此温度时效时,α相析出速度最快,仅需5 min。另外,该合金的时效响应快,在480～600℃时效时,α相从亚稳β相中析出的开始时间均少于30 min。
Metallographic method was used for the determination of TTT curve of Ti-6554 titanium alloy. The results show that the ＇nose＇ temperature of isothermal transformation is about 540 ℃. When the alloy is aged at 540℃, a phase precipitates fastest, and only 5 min is needed. Moreover, this alloy has fast aging response. When the alloy is aged at 480-600 ℃, the beginning time of a phase precipitated from metastable fl phase is less than 30 min.
