摘要
研究了淬火温度对 Ti 2 2 Al 2 7Nb粉末烧结合金的组织和热疲劳寿命的影响 .结果表明 ,在试验条件下 ,热疲劳寿命与 O相的形态有关 ;1 1 0 0℃热处理状态下的合金 ,O相最为细小 。
The effect of quenching temperature on the microstructure and thermal fatigue life of powder sinter Ti22Al27Nb alloy is investigated. As a result, under the test condition, the thermal fatigue is connected with the morphology shape of Ophase. After heat treatment at 1 100 ℃, the finest grain of Ophase and the highest fatigue life will be achieved.
