Metallurgy for Non-Specialists

Course Overview

This course is designed to introduce participants without a metallurgy background to the fundamental principles of metallurgy, materials behavior, and their applications in engineering and industry. It covers the relationship between material structure, properties, and performance, and provides practical knowledge of metals selection, fabrication, heat treatment, corrosion, and failure prevention.

By the end of the program, participants will be able to make informed decisions regarding materials use, quality, and performance, bridging the gap between metallurgists and non-technical professionals.

Course Objectives

Upon successful completion of this course, participants will be able to:

• Understand the basics of metallurgy and materials science.

• Recognize the structure, properties, and classification of metals.

• Identify common ferrous and non-ferrous metals and their applications.

• Understand mechanical properties and testing methods.

• Gain knowledge of heat treatment and its impact on material properties.

• Recognize causes of corrosion and methods of protection.

• Interpret metallurgical considerations in welding and fabrication.

• Appreciate metallurgical aspects of failure analysis and prevention.

• Make informed decisions on material selection, quality, and performance in engineering applications.
