Abstract : The problem studied concerns the establishment of a uniqueness theorem and a comparison theorem, which are essential in the construction of bounds, for a multiphase slab which is insulated on one face and is heated in an arbitrary manner on the other. The material is assumed to possess an arbitrary but finite number of transformation temperatures. Each phase of the material may have distinct thermal properties, and each change of phase is assumed to take place at a given temperature and may be accompanied by the absorption of heat. (Author)
