热分析法是研究合金结晶或相变过程的传统方法。铸造合金在冷却过程中,当发生结晶状态转变时,在温度——时间的冷却曲线上将出现转折、平台或回升。利用热分析法测定不同成分下合金的冷却曲线,确定其相交点,即可绘制二元合金的状态图。最早,大多数状态图的建立几乎无一例外地仰赖于热分析法。 Thermal analysis method is to study the crystallization of the alloy or the traditional method of phase transition. Casting alloy in the cooling process, when the crystallization state transition occurs in the temperature - time cooling curve will turn, platform or pick up. Using the thermal analysis of the alloy under different composition of the cooling curve to determine the intersection point, you can draw the binary alloy state diagram. Earliest, the establishment of most state charts almost invariably relied on thermal analysis.
