This is believed to be conneeted with the depletion of Mo, a scavenger of P, in matrix due to the Mo tithed carbides formation during preaging. Therefore, more P is released and segregated to grain boundaries. Carbide coarsening perhaps contributed to the increment in transition temperature too.

Mo可抑制磷的偏析，但因时效过程中富Mo碳化物的生成和长大，使基体中Mo的含量降低，因此，磷从Mo的&束缚&下&解放&出来并偏析到晶界，使脆性转变温度升高，此外，碳化物的粗化也可能导致脆性转变温度升高。

Based on the above investigation of ideal layer-by-layer growth process, the surface roughening phenomena during the real epitaxial growth are discussed. Some important microscopic dynamic models for molecular-beam epitaxy , which have attracted much attention recently, are studied. Using the master-equation method, the corresponding growth equations are directly derived, and then the scaling behaviors, the universalities, as well as the crossover effects are determined.
