Description
Learn the Principles and Rationale Behind Heat Treatment of Steel

Heat treatment is a critical step in steel processing that determines a material’s strength, hardness, toughness, and ductility. This course explains why heat treatment works, the science behind each process, and how it affects steel’s microstructure and properties.

Through clear explanations and practical examples, you will learn the rationale for choosing specific heat treatment methods, and how to apply them in real-world industrial contexts.

This course is ideal for students, engineers, and technicians seeking to understand heat treatment beyond the “how”, focusing on the why and the effects on material performance.
