差热分析法很早就应用于金属学领域,如测定金属熔点,确定合金相图等。差热分析法(Differential Therml Analysis)是热分析法的一种动态定性检测方法,简称DTA法。这种方法用少量的试样可以精确地检测出微小的热变化。用DTA法研究铝合金的时效析出过程是十分有效的。日本学者在这方面进行了大量
Differential thermal analysis has long been used in the field of metallurgy, such as the determination of metal melting point, determine the alloy phase diagram. Differential thermal analysis (Differential Therml Analysis) is a dynamic qualitative detection method of thermal analysis, referred to as DTA method. This method can be used with a small amount of sample can accurately detect small thermal changes. It is very effective to study the aging precipitation process of aluminum alloy by DTA method. Japanese scholars have done a lot in this area
