Abstract
In this paper, a new mathematical model recently outlined by the present authors 1 is applied to the case of unidirectional solidification via heat extraction through massive uncooled molds of effectively semi-infinite thickness. The model permits measurement of the Newtonian heat transfer coefficient at the metal/mold interface and a complete description of the kinetics and thermal characteristics of solidification is subsequently possible. Experimental results are compared with predictions for the case of lead and the effect of mold thickness in the effectively finite regime is also investigated.
