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.
