This creates larger temperature gradients between the surface areas, which are exposed to hot gases and the cooled inner zones (convection cooling, impingement cooling) and/or surface areas that are cooled by an air film. This results in higher thermal stress due to restricted thermal strain (<a id="temperatur-dependent-damage-mechanis…
