Introduction to Creep Fracture and Other Fracture Modes

  • Hermann Riedel
Part of the Materials Research and Engineering book series (MATERIALS)

Abstract

The acceleration of creep in the tertiary stage of the creep curve is often caused by the formation and joining of micro-cavities on grain boundaries. Creep fracture is therefore generally intergranular. The cavities may be nucleated early in the creep life, possibly even during the primary stage. Initially their effect on the creep rate is negligible but, as their number and size increase, they weaken the material progressively and finally induce failure. The nucleation and growth of cavities is studied extensively in Part II of this book.
