    摘要:

    利用銅模鑄造法制備 (La0.6Ce0.4)65Al10Cu25塊體非晶合金,通過X射線衍射和差示掃描量熱法對該非晶合金的熱穩(wěn)定性和晶化行為進(jìn)行研究。利用J-M-A方程對其等溫晶化動力學(xué)進(jìn)行分析,該合金平均Avrami指數(shù)在2.39~3.38之間。區(qū)域Avrami指數(shù)n(x) 分析表明,晶化初期n(x) 趨于3;晶化中期階段,n(x) 由2.5變化到3.5,在此過程中,當(dāng)2.5

    Abstract:

    (La0.6Ce0.4)65Al10Cu25 bulk metallic glasses (BMGs) were prepared by copper-mold casting. The crystallization behavior and thermal stability of (La0.6Ce0.4)65Al10Cu25 were investigated by X-ray diffraction and differential scanning caloricity (DSC). The isothermal kinetics was evaluated by the Johnson–Mehl–Avrami equation. The calculated Avrami exponents were in the range of 2.39 to 3.38. The average values of local Avrami exponents show that the value of n is about 3 at the initial stage; in the middle crystallization stage, the value of n changes from 2.5 to 3.5. In this stage, for 2.5
