It is necessary for two kinds of controlled cooling processing to possess air cooling phase to separate ferrite from austenite, and, by means of this, polygonal ferrite forms, the carbon concentration of the retained austenite untransformed increases and results in the stability of retained austenite increased.

在二种冷却方式轧后控冷的过程中，必须有一个α/γ二相分离的空冷阶段，使多边形铁素体形成，未相变奥氏体中碳浓度增高，其稳定性增强。

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.

初步研究表明：采用氨基储能体系，储/释过程无副反应，且储能介质能自然发生相分离；储热载体为流体，并可在室温下长期无热损储存，理论储能密度达66.5kJ/mol，远高于显热或相变蓄热；与其它热化学储能相比，吸热反应温度低，仅需650℃，而放热反应可产生500℃以上的高温，能量的储/释流量可随热源/负荷自适应变化，且可全天供热，更适合作为聚光式大规模太阳能热力发电中的能量储存系统。

Because of the melt property, the process of phase change is stable and controllable, the phase detaches will not happen easily.

这种熔融峰特征，使材料的相变过程较为平稳和可控，不易出现过冷现象和相分离。
