摘要
By modification of a numerical iterative computer simulation worked out for binary alloys, the solidification behaviour of ternary alloys can be quantitatively predicted. The program finds the cooling curves, the amount of binary and ternary eutectic, the concentration distribution of the solute elements in the dendrite arms and the spacing of the dendrite arms during and after complete solidification. Comparison of the numerical predictions with experimental results obtained for five alloys from the aluminium rich corner of the AlCuMg system at four cooling rates shows very good agreement. © 1990.
