摘要
A dissolution model of the plate-like and spherical second phases in the multiphase alloy during continuous heating process with constant rate has been proposed. The effects of heating rate and interface curvature on the concentration profiles in the matrix and the dissolution rate of the second phase were discussed. The model was applied to calculate the dissolved fraction of the second phase before melting during heating process. The calculated results for Al-5.8%Cu alloys, where the eutectic-melting fraction of the non-equilibrium eutectic was determined by DSC analysis, agree well with the experimental ones, clearly indicating the validity of the developed model.
