Tertiary creep is also called

WebThis part of curve occurs at high temperatures, so is also known as hot creep. This is also known as II stage or secondary creep. Tertiary creep is the last stage before creep fracture. The curve CD rises upward as rate of straining is too fast due to neck formation in the material. This is also known as III stage. Improving the Fatigue Life: i. Web13 Jan 2024 · For a long time, only empirical models existed for creep curves in the tertiary stage. To understand the role of creep damage, including changes in the dislocation structure, cavitation, and necking, basic models that do not involve adjustable parameters have, however, recently been developed.
