    摘要:

    本文研究了具有兩種不同組織(固溶態(tài)、時(shí)效態(tài))的Ti-3Zr-2Sn-3Mo-25Nb(TLM)合金在室溫應(yīng)變控制的低周疲勞循環(huán)變形行為及微觀變形機(jī)制。結(jié)果表明：TLM合金的循環(huán)硬化/軟化行為與應(yīng)變幅和組織密切相關(guān)。固溶態(tài)合金的低周疲勞壽命更高,且彈性模量均隨循環(huán)周次和總應(yīng)變幅的增大,從保持不變到急劇增加,時(shí)效態(tài)的彈性模量則在循環(huán)變形過(guò)程中基本保持不變。微觀組織特征表明,固溶態(tài)合金的循環(huán)變形機(jī)制主要依賴位錯(cuò)滑移、變形誘發(fā)的α″馬氏體和獨(dú)特的“Z”型β孿晶協(xié)同作用,而時(shí)效態(tài)合金則只是以位錯(cuò)滑移為主。

    Abstract:

    Cyclic deformation behavior and micromechanisms in strain controlled low cycle fatigue of a near β-Ti alloy Ti-3Zr-2Sn-3Mo-25Nb (TLM) with the different microstructures, which are solution treatment and aging treatment conditions, were comparatively investigated at room temperature. The results showed that the cyclic hardening/softening behavior of TLM alloy was significantly correlated with strain amplitude and microstructure.SThe low cycle fatigue life of the alloy at the solution treatment was higher, and the elastic modulus increased from constant to sharp with the increase of cycle number and total strain amplitude, while the elastic modulus of the aged alloy had a little change during the cycle deformation.SThe microstructure characteristics showed that deformation mechanism of the solid solution alloy was mainly dependent on the formation and their interaction of dislocation slip, the deformation-induced α martensites and the unique "Z" type β twin, while the aging alloy was mainly dependent on dislocation slip.
