Description
Many essential properties of iron alloys depend on the atomic mechanism of phase change. An understanding of this mechanism helps to improve the mechanical properties of steel. An useful technique to measure these atomic changes is dilatometry. This technique contributes to the study of iron alloys. In this module the key concepts of phase transformations in iron alloys will be explored. Mainly, the terms eutectic and peritectic.
Furthermore, the concepts of atomic arrangements, atomic movements and volume change during phase transformation will be explored. Finally, the dilatometry technique will be explained.
What you will learn
- Interpret the Fe–C equilibrium diagram, and the eutectic and peritectic diagram;
- Define phase transformation, identify atomic arrangements in metals;
- Distinguish volume changes during phased transformation;
- Interpret two techniques for atomic movement during FCC to BCC transformation.
