Cause of Heat Checking
(OP)
Have a question regarding the physics of heat checking. What I've seen in the literature is that it is due to alternating heating and cooling. However, I haven't seen anything that indicates whether it is influenced (and by how much) by rate of change of temperature rather than absolute temperature only. Also, is it an issue regarding thermal differential between the surface layer of the material vs a core temperature ?

We have various components in the Electric Power Generation industry that are exposed to this type of damage, where crack propagation basically stops at a certain depth, with no need for immediate repair.
