    摘要:

    本文針對某增壓器臺架耐久性考核240小時的直徑100mm的TiAl合金渦輪,通過對比分析考核前后渦輪輪轂芯部的微觀組織和力學(xué)性能,并結(jié)合未考核渦輪輪轂取樣的高溫持久試驗結(jié)果,評價了TiAl合金增壓器渦輪輪轂的耐久性。結(jié)果表明,在考核試驗后,渦輪輪轂芯部的微觀組織、洛氏硬度和室溫拉伸強(qiáng)度仍保持考核前的水平;同時,參照該型渦輪服役條件下的高溫持久加載后,試樣的層片組織仍保持完整,僅只在層片團(tuán)界析出了體積分?jǐn)?shù)0.5%的等軸γ晶粒??梢?,該TiAl渦輪輪轂具有良好的耐久性,能夠滿足應(yīng)用要求。

    Abstract:

    Based on TiAl turbocharger wheel with the diameter of 100mm after rig endurance test for total 240 hours, this paper evaluated the endurance of turbocharger wheel hub from the microstructure and mechanical properties. The microstructure and mechanical properties of the samples cut from the hub core of turbocharger wheel still retained a considerable level after endurance test. And the microstructure of the sample cut from the hub core of turbocharger wheel without rig test had an excellent stability after stress creep loading for 1000 hours at the actual working condition. So the hub of the turbocharger wheel had an condirable endurance that could meet the application requirement.
