The results show that: ( 1) after MA for 60 hours, single phase α-Fe nanocrystalline supersaturate solid solution powders ( 8.6 nm) can be obtained; 结果表明:(1)MA60h后,可获得单相α-Fe纳米晶(8.6nm)过饱和固溶体粉末;
The saturate and supersaturate characters of procaine penicillin G in sodium chloride aqueous solutions of different temperature, pH and concentration were investigated and analyzed by using laser detection technique. All of this provide the thermodynamic basis for studying on the reactive crystallization of procaine penicillin G. 采用激光测量装置研究了普鲁卡因青霉素在不同温度、不同浓度、不同pH值的氯化钠水溶液中的溶解与超溶解特性,为系统研究普鲁卡因青霉素溶液微粒结晶过程提供了一定的热力学基础。
The increasing of conductivity is the decomposition of the supersaturate solid solution contain Sc and Zr forming dispersion complex phase. 电导率的增加是含钪锆过饱和固溶体的分解形成弥散型的复相结构。
The reason for the hardness changing is the decomposition of the supersaturate solid solution contain Sc and Zr which is formed in solidifying process. The precipitated Al3 ( Sc, Zr) particles cause hardness increasing. Al-6Mg-Mn-Sc-Zr铸态合金在均匀化退火时有硬化现象,硬度变化的原因是凝固过程形成的含钪锆过饱和固溶体发生分解,析出的Al3(Sc,Zr)粒子导致合金硬度的增加。
A new phenomenon of re-dissolution of second phases and re-formation of supersaturate solid solution found in processes of severe plastic deformation was summarized. 综述了在室温强塑性变形过程中发现的新现象:第二相颗粒的回溶,合金基体重新形成过饱和固溶体。
Three exothermal peaks with different intensity appear in the DSC heating-up curves of MA powders. These peaks correspond to structural relaxation of distorted nanocrystalline supersaturate solid solution, nanometer grain growth and phase decomposition of solid solution, respectively; 在MA粉末DSC升温曲线中,分别出现3个强弱不一的放热峰,依次发生了畸变的纳米晶过饱和固溶体的结构弛豫、纳米晶粒长大以及固溶体的相分解过程;
However, a lot of micropores form in low-carbon MgO-C bricks after decarburization, and the high melting point MA is easy to supersaturate and deposite in the micropores. 而低碳镁碳砖碳氧化后形成微细化气孔,此微孔中生成的高熔点相MA容易过饱和而沉淀。
