相变

Cooling-curves of different composition after ultrasonic blend were measured with the guide of theory forecast results of the binary system of capric acid and myristic acid. The experiment phase diagram was protracted, eutectic temperature and composition range were discovered of the binary system. Phase change properties of eutectic composition were tested with DSC, the change of the wave shape of eutectic composition after 300 thermocycling was tested with IR.

The anisotropy inverted spectra will be determine, when the temperature reaches and goes beyond the temperature of phase transition for the NNPA and NIPA hydrogels that exhibit a LCST phase behaviors. The network is collapsed and the hydrated Cu ion is bound by network chains.

对于具有LCST相行为的NNPA 和NIPA水凝胶，当温度达到并超过其相转变温度时，即可测得其Cu自旋探针各向异性的ESR倒置谱，这种倒置谱是由于凝胶相变后，网格塌陷，网络缠裹水化Cu离子的结果。

According to DTA and the microstructure information, it is obtained that the phase transformation begins from 430.1℃,the solidus point of the alloy is 614.4℃, and the liquidus point is 636.4℃.

通过对AZ31镁合金DTA曲线的分析和不同温度下金相组织的比较、分析，确定了该合金的相变起始温度为430.1℃，共晶温度为438.5℃，固相线温度为614.4℃，液相线温度为636.4℃。

Combined with the analysis of recovered fragments,dynamic behaviors and spallation phenomena of these materials were studied.

研究表明，在实验加载压力范围内DT2和FeMnNi样品的自由面速度历史呈现包括相变波在内的典型三波结构，而对HR2钢，尽管金相分析显示其加载前后样品的相组织已发生变化，但速度剖面呈现的仅是典型的弹塑性双波结构。

Cooling below Ti=675℃, there appears an incommensurately modulated structure analogous to the incommensurate phase in K2WO4, K2MoO4, etc.
