Web19 Feb 2024 · Creep is a type of deformation that occurs in materials subjected to a constant load over time. The deformation is permanent and results in a change in the shape of the material. Creep is most commonly observed in metals, alloys, and polymers. It occurs when the molecules within the material are forced to move past one another. WebThese steels are prone to form secondary phases after exposures to temperatures ranging from 450 to 900 °C . The σ-phase is a hard, brittle non-magnetic intermetallic phase, with high Cr and Mo contents, affecting both hot and room temperature ductility. Some authors report that χ-phase precipitates for shorter times than σ and at slightly ...
