Description

Short description:
Explore failure mechanisms in carburised steels and learn how to prevent them.

Long description:
This module examines the causes of failure in carburised steel components and the criteria for selecting appropriate materials and processes. It explores the role of retained austenite, its impact on hardness, distortion, and dimensional stability, and methods for its evaluation and control. The module analyses failure mechanisms related to insufficient case depth, improper material selection, and inadequate core strength, including phenomena such as the “Thin Ice Effect.” It also introduces practical solutions to prevent failures, such as optimising carburising depth, selecting suitable alloy compositions, and applying stopping-off techniques to protect specific component areas. Additionally, learners are guided through the selection of carburising steels and their applications across different industrial contexts.

What you will learn

- Analyse the formation and effects of retained austenite in carburised components
- Evaluate causes of failure related to case depth and material properties
- Apply selection criteria for carburising steels based on application requirements
- Assess the impact of core strength and stress distribution on component failure
- Implement techniques such as stopping-off to control carburising outcomes
