Description
Short description:
Precipitation Hardening: Evaluate empirical methods to estimate yield strength increases from alloying in this self-paced module.
Long description:
This module explores the challenges and limitations of traditional equations, such as the Ashby-Orowan equation, in predicting strength increases due to precipitation hardening. Learners will evaluate the empirical alternatives available for estimating the increase in yield strength from microalloying in steels. Through simulation, theoretical analysis, and practical application, participants will engage with experimental data and formula derivation methods to address particle strengthening behavior. The module concludes with a detailed exploration of the impact of alloying elements and microstructural control in optimizing mechanical properties of steels.
