Description

Technical field: [0001] The invention relates to material testing technology, especially material fatigue testing technology. Background technique: [0002] Thermal fatigue refers to the restriction of the free expansion or contraction of the material caused by temperature changes. As a result, thermal stress is generated within the material due to the restricted deformation. When the temperature changes repeatedly, this thermal stress also changes repeatedly, thus causing the material to be damaged. High-temperature alloys are mainly used to manufacture various high-temperature components of aviation turbine engines and various high-temperature components of aerospace rocket engines. They are essential key components for modern aviation and aerospace engines. In aviation and aerospace engines, high-temperature alloys work for a long time under the action of high temperature and complex stress at 600~1200℃, and the conditions are relatively harsh. Especially when the combustion c...
