SUMMARY
Autofrettage is a process that enhances the elastic limit of materials, particularly in cylindrical structures, by inducing compressive residual stresses through heat treatment. This technique effectively reduces operating stresses, thereby improving the material's performance and lifespan. It is crucial to understand that increasing the elastic limit does not equate to altering the inherent elasticity of the material. If subjected to high temperatures, the induced residual stresses can be eliminated, reverting the material to its original state.
