求まる。これが熱解析法の原理である。The primary crystal temperature is the temperature at which crystallization begins when the molten metal is cooled.

初晶温度を求めることができる。The initial product temperature is detected by uniformly cooling the molten metal and measuring the temperature change over time, and finding the point where the temperature temporarily stops decreasing or the cooling rate changes. In other words, since the absolute value of the amount of heat required to crystallize a unit mass of alloy is greater than the absolute value of the amount of heat required to lower the unit temperature of a unit mass of molten metal, when cooling uniformly, The primary crystal temperature can be determined by utilizing the fact that the temperature drop temporarily stops at the primary crystal temperature.
