| Abstract: | The superheating in the melting of bulk Pb crystal without free surface has been studied. Effective methods for the preparation of the specimens are presented. Melting points of the samples were determined by a differential scanning calorimetre of the model DSC 7 with various speeds. It is found that kinetic superheating can occur in the system of bulk Pb crystal without free surface. |
