Critical Strain for Dynamic Recrystallisation. The Particular Case of Steels [PDF]
Metals, 2020 The knowledge of the flow behavior of metallic alloys subjected to hot forming operations has particular interest for metallurgists in the practice of industrial forming processes involving high temperatures (e.g., rolling, forging, and/or extrusion ...

Modeling of critical strain for dynamic recrystallization of niobium microalloyed steels
Materials Research Express, 2022 The critical strain for dynamic recrystallization (DRX) is most important in designing rolling schedules for the refinement of grain size by boundary-induced transformation mechanisms. Modeling of the critical strain for DRX from the stress-strain curves

Critical Infrastructures: Reliability, Resilience and Wastage
Infrastructures, 2022 By 2050, according to the UN medium forecast, 68.6% of the world’s population will live in cities. This growth will place a strain on critical infrastructure distribution networks, which already operate in a state that is complex and intertwined within ...

Prediction of steel flow stresses under hot working conditions
Materials Research, 2005 An austenitic stainless steel was deformed in torsion over a temperature range of 900-1200 °C using strain rates of 1, 5 and 10 s-1. The stress vs. strain curves determined were corrected for deformation heating and the flow stress was found to rise ...

A critical assessment of theories of strain gradient plasticity [PDF]
Acta Materialia, 2009 Theories to extend plasticity to the micron scale have been in existence for over a decade, complemented by a growing body of experimental data. Here, materials and mechanics aspects of two prominent strain gradient theories of plasticity, due to Nix and Gao and to Fleck and Hutchinson, are assessed within the context of simple bending.
