1. Surface attack includes oxidation, hot corrosion, and thermal fatigue . 2. Thermal stress weathering comprises two main types, thermal shock and thermal fatigue . 3. Supertherm has good thermal fatigue resistance above 1800 �F ( 980 �C ). 4. Military engine turbine blades experience two significant deformation stresses during normal service, thermal fatigue . 5. Thermal fatigue is when surface cracks occur on the die due to a large number of cycles.6. This decreases thermal fatigue , facilitates metal flow, and helps control the cooling rate of the casting metal. 7. Refractory bricks are typically replaced every five years, because thermal fatigue gradually introduces fissures that reduce the insulating strength. 8. He had set up the High Temperature Demonstrator Unit ( HTDU ) in 1972 to investigate cooling of turbine blades and thermal fatigue . 9. Further metallic components in the hot gas duct failed in September 1988, probably due to thermal fatigue induced by unexpected hot gas currents. 10. The resistance to thermal fatigue of this material is higher, but the quantity of slag when compared to the alloy between tin and lead.
