    摘要:

    采用差熱分析法(DTA)研究了具有高玻璃形成能力的Fe41Co7Cr15Mo14Y2C15B6塊體非晶合金的變溫晶化動(dòng)力學(xué)。由熱分析曲線得到玻璃轉(zhuǎn)變溫度Tg、晶化起始溫度Tx和晶化峰值溫度Tp1、Tp2，這些特征溫度具有明顯的動(dòng)力學(xué)效應(yīng)。運(yùn)用Kissinger法和Ozawa法分別計(jì)算出不同升溫速率下該Fe基塊體非晶合金的玻璃轉(zhuǎn)變激活能Eg、晶化激活能Ex與激活能Ep1、Ep2。采用Kissinger方法和Ozawa方法解釋了此大塊非晶合金具有高的熱穩(wěn)定性的熱力學(xué)機(jī)制。

    Abstract:

    The non-isothermal crystallization kinetics of Fe41Co7Cr15Mo14Y2C15B6 bulk amorphous alloy with high glass forming ability was studied by the differential thermal analyzer (DTA). Glass transition temperature Tg, onset crystallization temperature Tx and peak crystallization temperature Tp1 and Tp2 were obtained from DTA curves. These characteristic temperatures were of obvious dynamic effect. The glass transition activation energy Eg, crystallization activation energy Ex, and activation energy Ep1, Ep2 corresponding to characteristic temperatures Tg, Tx, Tp1, Tp2 were calculated by Kissinger and Ozawa equations, respectively. The thermodynamics mechanism of Fe41Co7Cr15Mo14Y2C15B6 bulk amorphous alloy with high thermal stability was explained by Kissinger method and Ozawa method.
