利用多通道数据采集仪对几种熔铸炸药冷却过程温度场进行测试,发现熔铸炸药冷却过程特别是相变发生的瞬间,温度曲线发生较大的拐点变化,通过对实验数据的分析,探讨了相变发生机理,得到了几种熔铸炸药的相变温度,随着熔铸炸药固相含量的增加,相变温度有下降趋势.所探讨的的两种熔铸炸药的相变温度在76～77 ℃内,均低于TNT的熔点.

Multiple channels data collecting instrument has been used to investigate the temperature distribution of melt-cast explosive during the cooling process under various cooling conditions. The most valuable inflexion point of the temperature curve was obtained during the cooling process,especially at the moment when the phase transformation occured. Through the analysis of the experiment data,the mechanism of the phase transformation and that several temperatures of the phase transformation of melt-cast explosive were obtained. Phase transformation temperatures tend to decline along with the increase of the content of melt-cast explosive. Phase transformation temperatures are 76-77 ℃,which are both under the TNT melting point.
