摘 要: 简要介绍了利用差示扫描量热法(differential sanning calorimetry,DSC)中的连续测试法测量等压热容的基本原理,实验分析了恒温段的设定条件、升温速率、样品致密度、样品特性等因素对等压热容结果的影响。最终得到了一组通用且合理的实验参数,为后续采用DSC测量不同体系的等压热容数据奠定了坚实的基础。
关 键 词: 冶金物理化学;差示扫描量热法(DSC);等压热容;影响因素

Abstract: The basic principle of continuous test method in differential scanning calorimetry (DSC) for measuring isobaric heat capacity was briefly introduced in this paper. The effects of setting conditions in the constant temperature section, heating rate, sample density and sample characteristics on the isobaric heat capacity results were analyzed by experiments. Finally, a set of general and reasonable experimental parameters was obtained, which laid a solid foundation for the subsequent DSC measurement of isobaric heat capacity data in the different systems.
Key words: metallurgical physical chemistry; differential scanning calorimetry (DSC); isobaric heat capacity; influencing factors
