Isothermal coarsening of liquid inclusions in aluminium-copper alloys

  • P. C. Wilson

An isothermal coarsening model was introduced for liquid inclusions in homogeneous aluminium-copper alloys. Discrepancies between experimentally measured and analytically predicted variations of the solid-liquid interface area per unit volume of liquid,Sv, the average inclusion diameter,¯D, and the number of inclusions per unit volume of solid,Nv, with isothermal coarsening time were attributed to experimental evaluation errors, to the inaccuracy of some assumptions made or values adopted for certain system variables and to the effect of melting and solidification kinetics. At constant fraction liquid, isothermal coarsening slows down with increasing copper concentration.
