Description
Short description:
Investigate how grain size affects steel toughness and UTS through ITT prediction models and mechanical property analysis.
Long description:
This module explores the influence of grain size on the mechanical properties of steel, with a focus on toughness and Ultimate Tensile Strength (UTS). Learners will examine the correlation between grain refinement and Charpy Impact Transition Temperature (ITT), including empirical equations used to predict ITT in steels with varying alloy compositions. The module introduces the Mintz, Baird & Cochrane models and investigates how manganese, silicon, and nitrogen levels influence ITT. Learners also assess grain size effects on work-hardening behavior and UTS using multiple linear regression models. Finally, the module highlights how grain size interacts with rolling direction and microstructural inclusions, reinforcing the complexity of structure-property relationships in steels.
