The results show that ordered phases precipitated and formed a pseudobinary system; precipitated earlier than g phase by a congruent ordering + spinodal decomposition mechanism and thus produced a nonstoicheometric ordered phase, then the nonstoicheometric g phase precipitated by a non--classical nucleation and growth mechanism at the boundaries of phases, meanwhile, both of them transformed to stoicheometric ordered phases.
研究发现该合金沉淀过程中,析出D022结构的(Ni3V)相和L12结构的Ni3Al相,二者构成伪二元系;相先于相析出,相的沉淀机制为等成分有序化+失稳分解,相在相的相界处非经典形核,二者均先形成非化学计量比有序相,之后向化学计量比有序相转变;随Al浓度增加,相析出变慢,所占比例减少,而相反之,析出越来越早且所占比例增加。

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.
