Lämpötilacykli, or temperature cycling, refers to the process of repeatedly exposing a material or object to variations in temperature. This can involve cycles of heating and cooling, or alternating between high and low temperature extremes. The rate and magnitude of these temperature changes are key parameters that define a specific thermal cycling regime.

The purpose of temperature cycling can vary. In material science and engineering, it is often used to test the durability and reliability of materials and components. Repeated thermal stress can induce fatigue, leading to cracks, delamination, or changes in material properties. This type of testing is crucial for ensuring that products can withstand the temperature fluctuations they will encounter during their operational lifespan, such as in aerospace, automotive, or electronics industries.

Beyond testing, temperature cycling can also be an intentional process for modifying material characteristics. For example, controlled thermal cycling can be employed in heat treatment processes to alter the microstructure and mechanical properties of metals, ceramics, or polymers. Annealing, tempering, and aging are all examples of processes that involve specific temperature cycling profiles to achieve desired material performance. Understanding the effects of temperature cycling is therefore fundamental to both material development and quality assurance.
