N2 - Grain growth in dual-phase structures has been studied by computer simulation techniques using a two-dimensional lattice model. Grain coarsening in each phase follows the cube power law. This is the result of mutual retardation of grain growth and is affected by the mutual wettability of both phases which in itself is a function of the interfacial energy ratios ραα/ραβand ρββ/ραβbetween the two phases.(FORMULA PRESENDED) has been obtained. It is shown that computer simulation results and experimental data on the radii of austenite and ferrite grains in dual-phase low-alloy steel and duplex stainless steel agree well with the proposed relation.
