The ways in which strengthening mechanisms contribute to the yield strength of a given steel, and how they can be used to create required combinations of strength and toughness of steels for a variety of structural applications will be examined.
Precipitation Hardening
Full Code
MET0205220
Module Type
E-learning
Description
The time needed to make measurements of particle size using TEM is often prohibitive and sizes and particle density measured from micrographs from a particular process route are only rarely directly applicable to a different one. Various authors have used nomograms for estimating the contribution from precipitation strengthening from the alloying addition and making assumptions about the average particle size. In this module different TEM measuring precipitates will be showed and explained. Then, two methods for estimating Precipitation Hardening will be presented. One of them is theoretical and the other is experimental.
Finally, Solid Solution Hardening will be introduced.
What you will learn
- Identify grain boundary, precipitation and array particles in a TEM image;
- Recognise the differences between experimental and theoretical estimating precipitation hardening method;
- List the Solid Solution Hardening (SSS) main factors.
