Metallurgy For Non Metallurgists

Category: Aci Code Requirements And Specifications For Concrete Design, Construction And Repair Training

Course Description

This program will provide an integrated practical overview of metals and alloys and relating it to the mechanical and physical characteristics of metals; starting from materials testing and physical/mechanical properties, through corrosion properties and strength/deformation principals, and to ferrous and nonferrous alloys and heat treatment.

The course will then include ferrous alloys (plain and alloy steels, Stainless steels and cast irons) and nonferrous alloys (for corrosion and high temperature applications, such as nickel, cobalt and titanium based alloys). The nature of hot and cold working of metals and heat treatment, including annealing, normalising, tempering and case hardening will be explained.

The fundamentals of corrosion and corrosion prevention will also be presented in practical terms with examples to illustrate the key points.

The behaviour of metals under various loading conditions (static, dynamic, fracture) will be presented and related to design methodology and procedures; rules of thumb, standards, and best industry practices.

Each of the major topics will be presented as individual units, and in the context of the overall usage of metal components and structures and failure mechanisms, and mechanical integrity.


Upon completion of this course, participants will have gained an understanding of the important principals of engineering involving properties and characteristics of metals and alloys, including fabrication and heat treatment of commercial steels and non-ferrous alloys.

Participants will acquire sufficient knowledge and skills to independently evaluate possible metallurgical and design solutions, to recognise crucial metallurgical phenomena and intelligently discuss their metal problems with design engineers, metallurgists and fabricators.
