High temperature creep behavior of Inconel 617 and Haynes 230
… on the biaxial, long term, high temperature creep behavior for Alloy 617 and Alloy 230. The creep mechanisms, including dislocation creep and grain boundary sliding, were found for the stress range of 10 to 55 MPa at 850oC, 900oC and 950oC for Alloy 617. In the contrast, only dislocation …

Creep and anelasticity of conventional and ODS steels
… mechanical stresses provide conditions for creep deformation to be significant as to become a key factor limiting the lifetime of the material. At the same time, components in nuclear power plants are subject to cycles of start-up and shut-down, due to operations of maintenance, refuelling, …

The modelling of damage due to diffusional creep in high chromium steels
Understanding the creep deformation of high chromium steels in use in modern power plants has become important in predicting the behaviour and stability of these materials over their operational lifetime. At the deformation rates and conditions recorded in modern power plants, diffusional creep by …

Packing of particles during softening and melting process.
… deformation of the bed behaves the theory of creep deformation. 7. A mathematical model for predicting bed porosity change due to softening deformation based on creep deformation theory has been developed. 8. Increase in load pressure also reduces the peak contact face number of the …

Mitigating high-temperature, high-pressure hydrogen attack
… high-pressure hydrogen attack is a degradation mechanism that threatens the integrity of critical components in re fineries and petrochemical plants. This phenomenon was discovered in the early twentieth century, however, the experience-based recommended practice used to design for such …
