Description

Short description:
Explore the origins of carburising and learn how early heat treatment processes improved steel properties.

Long description:
This module introduces the historical development and fundamental principles of carburised steels. It explores how early blacksmiths, through experimentation, discovered methods to enhance the mechanical properties of tools by manipulating heat and carbon exposure. The module explains the evolution of carburising techniques, including the use of carbon-rich environments, and provides a foundational understanding of quenching and tempering processes. Learners will examine how these heat treatment methods influence microstructure, hardness, and toughness, and how visual indicators such as oxide colours were historically used to assess tempering temperature. The module concludes by linking these early practices to modern metallurgical understanding of surface hardening.

- Describe the historical development of carburising techniques in steel processing
- Explain the principles of quenching and tempering and their effects on steel properties
- Analyse the relationship between heat treatment processes and resulting microstructures
- Interpret visual indicators such as oxide colours to estimate tempering temperature
- Assess how carburising improves hardness and durability in steel tools
