Which component is likely to undergo elongated deformation due to heat and centrifugal force?

Turbine blades are designed to operate in high-temperature environments and experience significant centrifugal forces due to the high rotational speeds of the turbine. As the engine operates, the turbine blades not only endure the intense heat generated from the combustion process but also the mechanical stresses associated with their rotation in a dynamic environment. These factors can lead to elongated deformation if the material properties are tested beyond their limits.

The unique design and material of turbine blades, typically made from superalloys or ceramics, are intended to withstand these conditions, but under certain circumstances, such as prolonged exposure to high temperatures or suboptimal cooling, deformation can occur. Elongation of the blades can affect their aerodynamics and structural integrity, potentially leading to performance issues or failure.

Understanding this behavior is crucial for the maintenance and design of turbine engines, as manufacturers must ensure that the materials and designs can tolerate the stresses encountered during operation. This is not as pronounced in the other components mentioned, which experience different types of stresses and thermal dynamics in their respective operational contexts.
