The mechanism of solid - state displacement reaction has been studied , the solid - state displacement reaction path has been analyzed , the mechanical properties of composites has been tested Mo - si - c三元系稳定性化学势相图是定量分析mo _ 2c - si固态置换反应反应路径的重要手段。
Therefore , it is impossible that the microstructure of mosi2 - sic composites prepared by solid - state displacement reaction are interpenetrating structure . 6 因此,在1200通过固态置换反应原位制备的mosi _ 2 - sic复合材料的微观组织不可能是内联型组织( interpenetratingstructure ) 。
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。
4 . experimental data analysis and theoretical calculation indicated that the interface micro - structure of the solid - state displacement reaction between mo2c and si can be explained properly by the new theoretical model : rate - control - elements convergent diffusing model 实验数据分析和理论计算表明,本文提出的“速率控制元素非平行扩散模型”可以很好地解释mo _ 2c - si固态置换反应的微观界面结构。
