Traveling Zone Method

When distance traversed by the zone x Z, the composition of the solid will equal Colt the starting material is macroscopically homogeneous but microscopically inhomogeneous (e.g., a pressed powder sample with two or more components), a single pass 

Composition profile (upper) and local melting temperature (lower) of material being processed by the traveling zone method. If the material in the molten zone is completely mixed, its composition will be Co/k and it will have the same melting temperature as the newly formed solid when steady-state growth is achieved. Since the material in the zone is not constitutionally undercooled, interfadal breakdown is not a problem.

For the above reasons, temperature of the monomer far from the incoming front is a more significant parameter to be checked. Indeed, if a temperature increase happens in regions distant from the hot travelling zone, SP is probably taking place. A convenient method to verify the occurrence of that is given by the analysis of temperature profiles (Figure 1).
