论文摘要
铁动力学模拟了铁中的氮病和碳化钛沉淀的动力学。分别在奥斯丁岩和铁氧石中用于碳化物的果核酸盐，分别用于碳化钛，分别在奥斯丁岩中进行的模拟，以依赖温度，溶质浓度和初始簇分布的依赖性。结果显示了不同的温度和溶质浓度，并将其与可用的实验数据进行了比较。它们的初始簇分布几乎没有一定的放松时间的影响，并且高度稀释的合金只有单体具有明显不同的行为，而稀释合金或合金具有不同的初始簇分布。
Kinetics of niobium and titanium carbide precipitates in iron has been simulated with cluster dynamics. The simulations, carried out in austenite and ferrite for niobium carbides, respectively in austenite for titanium carbide, were analyzed for dependency on temperature, solute concentration, and initial cluster distribution. The results are presented for different temperatures and solute concentrations and compared to available experimental data. They show little impact of initial cluster distribution beyond a certain relaxation time and that highly dilute alloys with only monomers present a significantly different behavior than less dilute alloys or alloys with different initial cluster distribution.
