0.474Zr0.34- Cu0.06Be0.126)100-xFex（x=0，2）金屬玻璃復(fù)合材料。通過引入Fe元素，提高了β-Ti相的穩(wěn)定性。此外，還發(fā)現(xiàn)了一個(gè)異常的內(nèi)耗峰，這是由于在亞穩(wěn)的β-Ti相中析出ω-Ti所引起的。在玻璃化轉(zhuǎn)變溫度Tg以下，由于相變和非晶基體部分結(jié)晶的耦合效應(yīng)，2種金屬玻璃復(fù)合材料的儲(chǔ)能模量均表現(xiàn)出異常過沖行為。所得結(jié)果為更好地理解內(nèi)生亞穩(wěn)β-Ti型金屬玻璃復(fù)合材料的復(fù)雜動(dòng)態(tài)力學(xué)弛豫行為提供了借鑒。;To understand the dynamic mechanical properties and thermodynamic stability of β-Ti phase-embedded Zr/Ti-based bulk metallic glass composites (BMGCs), (Ti0.474Zr0.34Cu0.06Be0.126)100-xFex (x=0, 2) BMGCs were prepared and investigated. Results show that by introducing Fe element, the stability of β-Ti phase is improved. An abnormal internal friction peak can be observed due to the precipitation of ω-Ti in the metastable β-Ti phase. Below the glass transition temperature Tg, both BMGCs show abnormal overshoot on storage modulus due to the coupling effect of phase transition and partial crystallization of amorphous matrix. This research provides information about the complex dynamic mechanical relaxation behavior of the in-situ metastable β-Ti BMGCs."/>
