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.
