Materials and Metallurgical Engineering is a broad discipline that studies materials, including metals and non-metals, their extraction, production, manufacturing of components, recycling, economics, environmental stability and applications in various aspects of human life.
This branch of engineering consists of development of metallic, ceramics, polymeric and composite materials. It studies the traditional materials including steel, cast iron, copper, aluminium, titanium, magnesium, etc and their alloys as well as the non-metals, plastics, ceramics, glass and is continually developing new materials to meet different design conditions.Expanded researches in the field are focusing on biomaterials, smart functional materials, nanocomposites, superalloys, electro-ceramics etc. These materials are processed to obtain desired properties and structures. Appropriate selection, methods of production, heat treatment and finishing are applied to meet needs of transportation, medicine, clothing, recreation, food production, power generation, communication, housing, and other areas of life.It is using expanding technological advancement in microscopy, spectrometry and chromatography to study the structure of materials and establish material properties for different usages.
Nigeria is endowed with abundant natural resources. The solid minerals resources require expertise to harness them for sustainable national development. A measure of a nation’s economic growth and power is a function of her production of metals and materials as a whole and the per capital output. Materials and metallurgical engineers are the major players needed to achieve the responsibilities of industrialization and national development through the materials and metallurgical industry.
The Department aims to train students in fundamental engineering principles that will contribute to development of the vast resources spread across the nation and globally.
