Description
In the Ashby-Orowan equation different problems are introduced because of the simplifications included in the formulation or in the way that you can measure different parameters to introduce in the equation. To improve the prediction of strength that can be expected from a given addition of a microalloying element or by precipitation on iron carbides or nitrides, experiments are required. In this module different problems with the Orowan equation will be introduced. Then, an empirical approach will be proposed to improve the strength prediction. After that, different results will be showed to compare the predictions and the experiments. Finally, increase in flow stress determination will be treated experimentally and theoretically.
What you will learn
- Try an Empirical Approach to Particle Strengthening;
- Explain about Increase in Flow Stress Determination.
