摘　　要：针对传统实验"二元合金相图"在教学中存在的问题进行改进,采用程序升温加热系统来控制样品的熔化过程,利用计算机及自编程序软件实现了样品冷却过程温度数据的在线采集及步冷曲线的同步显示,改进后的系统用于本科实验教学取得良好的教学效果。In this paper,the problems in the traditional experimental teaching method of ＂binary alloy phase diagram＂ are improved.By using a temperature programmed system to control the heating process of tested sample and developing computer and programming software to record the experimental data and to display images of step-cooling curves synchronously,an excellent experimental teaching effect has been obtained by applying the improved system into the undergraduate experiment teaching.

关 键 词：二元合金相图 实验改进 教学效果
