A new type of structure of the solid - stale displacement reactions which named spiral - mtergrowth - aggregate structure was discovered in the mo2c - si diffusion couple and was considered as the result of spinodal - decomposition continuous phase - transformation 昆明理工大学博士学位论文2002 . 5摘要6 .初步发现了一种新的固态置换反应形貌结构:螺旋共生束集型结构。
Moreover , reaction path analysis was accomplished on the fundamental base of the theoretical calculation for mojsi / t phase - interface in the diffusion couple mo2c - si at 1200c . 5 . interface stability analysis of solid - state displacement reaction shows that the layered structure of solid - state displacement reaction between mo2c and si ( fig . 6 . 8 ) is not stable 利用模型进行的1200 , mo _ 2c - si扩散偶mo _ 4si _ 3 / t相界面的分析计算,为反应路径的细致分析奠定了坚实基础,这也是该理论模型应用于实际束集型结构分析的引人注目之处。
