The thermal shock resistance of a material represents its resistance to rapid, abrupt changes in temperature. Thermal shocks accordingly lead to mechanical stresses in the workpiece, mainly between the outer and inner area or the core of the workpiece. The reason for this is that heat can be transferred or dissipated more quickly to the surface than to the core. If the stresses that arise in this way exceed the critical value of the parameter, the workpiece can be damaged.
