Learn how the changes in the grain size affect the mechanical properties.
Grain Size, Toughness and Ultimate Tensile Strength
Full Code
MET0201225
Module Type
E-learning
Description
In material science, Toughness is the total deformation energy that is capable of absorbing or accumulating a material before reaching rupture under impact conditions, due to the accumulation of dislocations. This is closely related to grain size and temperature, too. In this module the Charpy Impact Transition Temperature (ITT) will be introduced. The equations that describe the ITT will be showed. The Mintz, Baird & Cochrane results will be studied.
The effects of grain size on work-hardening rate & UTS will be presented. Finally, the UTS and true stress/true strain curves will be displayed.
What you will learn
- Interpret how Grain Size affects Toughness;
- Evaluate the Charpy Impact Transition Temperature (ITT);
- Recognise how Grain Size affects Ultimate Tensile Strength.
