| Abstract | One of the most difficult tasks a material scientist must complete is designing materials for high temperature applications. The desired microstructure tends to deteriorate as a result of several thermodynamic and kinetic variables. This is due to the fact that diffusion, among other underlying processes, has a temperature-dependent exponential kinetics. Therefore, in this chapter we will mainly discuss the creep and superplasticity phenomena to design the material for different potential applications. Further, factors affecting the creep, effect of stress and temperature on the creep curve, creep mechanism of crystalline material, creep resistant material, and creep in nanomaterials are discussed in detail. Creep is defined as permanent distortion (plastic deformation) of a material over time under a constant load or stress. In certain ways, the phenomena of creep and superplasticity are related: in the case of creep, damage accumulation can result in sample failure, but in the case of superplasticity, extended plastic deformation can be accomplished (damage accumulation leading to failure is postponed). Moreover, we have illustrated the superplastic materials, which shows the extremely large tensile elongation before failure. Furthermore, we have outlined the superplasticity mechanism in polycrystalline material, and in nanomaterials. |
