【摘要】 采用分子动力学方法对In在相同初始状态下以不同速度冷却的凝固过程进行了模拟研究。以2.56×1013,2.56×1012Ks的速度的冷却,得到非晶态结构;以2.56×1011Ks的速度冷却,发生了明显晶化现象,玻璃转变温度约为300K。这一结果,对于如何正确选择冷却速度获得优良材料性能,将具有实际意义。更多还原

【Abstract】 The effects of different cooling rates and the same initial conditions during solidification process of In has been studied by the moleular dynamics method. It has been found that:the amorphous structures are formed with 2.56×1013?2.56×1012 K/s cooling rate.While the crystal structures are formed with 2.56×1011K/s cooling rate.These results will have important practial significance to choose coo1ing rates correctly in order to obtain excellect mocroscopic properties.更多还原
