Multiscale study on Phase Transformation of Ceramic Materials

Compared with their microstructures, phase analysis of ceramic materials is rarely reported. Generally, phase analysis includes experimental phase structure determination and theoretical simulation, which are quite challengeable and require a heavy workload. Here, we proposed a series of simulation methods to analyze the phase transformation during the sintering process of Al₂O₃-ceramic materials. The structures of generated Al-Mg phases were simulated using XPFC method. The obtained potential function of Ti-C-N was applied to simulate the formation of generated Ti-C-N phases with MD methods employed. Combined with corresponding experimental results, the relationship between specific phases and mechanical properties were established.
