MET0205205

Module Type

E-learning

Description

Short description:
Explores precipitation and solid solution hardening in steels through TEM analysis and strengthening theory.

Long description:
This module introduces the fundamental mechanisms used to strengthen steels, focusing primarily on precipitation hardening. Learners explore the theoretical and experimental foundations of precipitation strengthening, analyze TEM micrographs, and estimate particle contributions to yield strength. It also introduces Solid Solution Hardening and the key parameters that influence this process. Emphasis is placed on interpreting metallurgical data and applying nomograms for engineering predictions in steel alloy design.

What you will learn

- Identify grain boundary, precipitation, and array particles in a TEM image.
- Differentiate between theoretical and experimental methods for estimating precipitation hardening.
- Apply nomograms to estimate the contribution of precipitation strengthening in steels.
- List key factors influencing solid solution hardening in ferritic alloys.
- Analyze TEM micrographs to evaluate particle size distribution and alignment.
- Compare mechanical strengthening contributions using experimental yield strength data.
