摘      要：Kinetic behaviors of niobium and titanium carbide precipitates in iron are simulated with cluster *** simulations,carried out in austenite and ferrite for niobium carbides,and in austenite for titanium carbide,are analyzed for dependences on temperature,solute concentration,and initial cluster *** results are presented for different temperatures and solute concentrations,compared to experimental data *** show little impact of initial cluster distribution beyond a certain relaxation time and that highly dilute alloys with monomers only present a significantly different behavior from denser alloys or ones with different initial cluster distributions.
