摘要
研究了Mg65Cu22Ni3Y10非晶态合金在连续升温过程中的晶化行为.结果表明,随升温速度的加快,特征温度Tg、Tx、Tp均向高温区移动,其过冷液相区的宽度也逐渐增加,表明该非晶合金的晶化具有明显的动力学效应.利用Kissinger法和Ozawa法分别计算了合金的晶化峰值激活能,所得结果偏差不大.利用Flynn-Wall-Ozawa法得到该合金的晶化激活能E(x)随晶化体积分数x变化的关系曲线.
The crystallized behavior of amorphous alloy Mg65 Cuzz Ni3 Y10 during continuous heating was investigated. The result showed that, with increasing of heating rates, the characteristic temperatures （ Tg, Tx and Tp） shifted to high temperature region, and the supercooled liquid region increased. It was obvious that this amorphous alloy had a dynamic effect. Using Kissinger and Ozawa plots, the activation crystallization energy could be evaluated, resulting in a small deviation between them. Using the Flynn-Wall-Ozawa method, the relationship between the activation crystallization energy E（x） and the crystallized volume fraction x during continuous heating of amorphous alloy Mg65Cu22Ni3 Y10 could be obtained.
