非晶Zr50Al10Ni40的结晶动力学,通过等温和等时差示扫描量热法测量,使用一个新的程序,涉及应用模块化的分析模型,以提供一个完整的描述的相变动力学,结合前面的分析的转化率最大值进行评估。详细分析的转化率最大值的位置,作为一个功能的转化分数的权力,证明了通过识别的操作冲击模式。在此基础上,控制结晶动力学的动力学参数,然后可以确定定量使用模块分析模型。通过适当控制结晶条件,可以改变结晶控制机制。所获得的结果是一致的微观结构的演变,通过透射电子显微镜观察。
The crystallization kinetics of amorphous Zr50Al10Ni40, as measured by means of both isothermal and isochronal differential scanning calorimetry, were evaluated using a new procedure involving application of a modular analytical model to provide a complete description of the phase-transformation kinetics, in combination with a preceding analysis of the transformation-rate maximum. The power of detailed analysis of the position of the transformation-rate maximum, as a function of the transformed fraction, was demonstrated by identification of the operating impingement mode. On this basis, the kinetic parameters governing the crystallization kinetics could then be determined quantitatively using the modular analytical model. The crystallization governing mechanisms could be varied by appropriate control of the crystallization conditions. The results obtained are consistent with the microstructural evolution, as observed by transmission electron microscopy.
