- what is creep deformation and under what general conditions it is likely to occur in metals and ceramics?
- Creep is a slow, irreversible deformation that occurs at stress levels below yield strength.
- Creep deformation occurs at >30% of melting temperature for metals and >40% of melting temperature for ceramics
- Creep deformation accumulates over time
- Describe what factors influence the extent and rate of creep in metals and ceramics?
- material properties and microstructure, operating environment and applied stress
- These combine to determine the dominant mechanism of creep
- State and explain the four engineering design scenarios in which creep performance is…
