An integrated practical overview of metals and alloys will be given in this program, along with a connection to the mechanical and physical properties of metals. Materials testing and physical/mechanical properties will be the starting point, followed by corrosion properties, strength/deformation principles, ferrous and non-ferrous alloys, and heat treatment.

Course Objectives:

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 recognize crucial metallurgical phenomena and intelligently discuss their metal problems with design engineers, metallurgists and fabricators.

Delegates will enhance their competencies in the following areas:

Understand the fundamental bases of mechanical testing
Compare mechanical properties of metals for selection purposes
Gain an understanding of the nature of metallic bonds and crystal structures of metals
Understand the solidification process of pure metals
Learn of examples of probable defects that may occur within the solidified structure of a metal
