An alloy solidification problem is considered in a semi-infinite medium for a substance haying an extended temperature range between the solidus and liquidus temperatures. The analysis in the mushy gene has been performed by dividing the zone into two regions since the structures in the mushy gone are different depending upon the region where it is close to the solidus front or liquidus front. The solidus fraction in the mushy zone is assumed to be a linear function of temperature. The temperature distribution in each region is determined and the movements of the solidus and liquidus fronts are obtained as a function of time.
