High creep resistance

Webhigh-temperature strength properties should be given priority; creep or creep-rupture (sometimes called stress-rupture). If the component is small and/or the tolerances very close, such as in turbine blades, creep is regarded as the overriding factor. But if the component is large and capable of accommodating greater deformation, such as shell-and- Creep can occur in polymers and metals which are considered viscoelastic materials. When a polymeric material is subjected to an abrupt force, the response can be modeled using the Kelvin–Voigt model. In this model, the material is represented by a Hookean spring and a Newtonian dashpot in parallel. The creep strain is given by the following convolution integral:
