| Objectives of the Course | |||||
| The objective of this course is to understand, analyze, and correctly apply heat treatment processes to improve the mechanical and physical properties of steel materials. The course covers topics such as fundamental heat treatment operations, TTT (Time-Temperature-Transformation) diagrams, continuous cooling diagrams, heat treatment environments, hardening, martensitic transformation, tempering, hardenability, cold working and annealing, aging, thermomechanical processes, and heat treatment diagrams for commercial alloys. Students are expected to gain theoretical knowledge and develop practical skills in applying heat treatment methods that enhance the performance of steel materials and make them suitable for industrial applications. | |||||
