Metallurgical and Materials Engineering Dept.

Metallurgical and Materials Plant and Process Design (MME 503) is a compulsory final year course in the department, mounted to ensure that students are taught the specifics, and put to the actual task, of designing in the real world of metallurgical and materials engineering. This is a major curriculum requirement in training an engineer. It is an applied course, in which students must draw on the metallurgical engineering scientific and technical contents of the various courses taken (and will be taking in this same semester), to tackle typical plant design tasks. The typical plant problems are formulated with local content reality and entrepreneurial opportunities in mind, so that the training will have high applicability to the scenarios the students can find themselves after graduation. The formal class sessions will present general principles and tools in metallurgical engineering plant design (process design, equipment design, mass balance principles, energy balance, profitability, layout, CAD drawing, etc.) and provide detailed guidance for executing the specific design tasks. Students will work in groups; each group on its chosen plant design task. The taught aspect of the course will be assessed via quizzes, tests and examination, while the practical design task will be assessed by a design write-up and design defence presentation. Tones and approach to business in the course are deliberately pitched towards that of professional course training of plant designers to impart the psyche.

This course is to provide an understanding of the principles that determine the evolution of microstructres in metals during various processes and their relation with its property and applications in engineering services. The proper understanding of nucleation and growth in solid materials will be imparted.. Students will be taught the mechanism, kinetics and characteristics of pearlitic, bainitic and martensitic transformations. The mechanism of tempering will be studied. The physical Metallurgy of alloy steels, aluminium alloy, and copper alloys will be covered.

The emphasis will be on the rational utilization of technology as economic resource in Nigeria The course will reflect commitment and aspirations of the government and people of Nigeria to deploy S&T as the fulcrum of all activities that can be geared towards realizing the nation’s potentials as a regional power in Africa, emerging as a global economic power within a short time. Technology Policy & Planning as course will provide the knowledge of building a nation that is able to provide steadily and on a progressive basis, high standard of living and quality of life for its citizens by harnessing science and innovation outputs as well as the energies and talents of its highly resourceful people.

Refractory Technology (MME 525) is an optional elective course available in the department designed to enable interested students have more detailed knowledge in refractory production, use and related material science governing these. It is structured on the background general knowledge that the current students would have had in Fuels, Furnaces and Refractories (MME312). Hence the course draws on that background knowledge to move on to the relatively more indepth details of how inherent properties refractory minerals affects/dictates suitable technology in the course of the production. The inherent properties and production specifics combine to determine applications for the various refractories in the various service demands and environments encountered in the materials processing furnaces, ovens, kilns and stoves. These are all correlated in the course. Being a special elective of the last semester of a B. Eng. Degree training, the scientific and technical content are pitched towards that of professional course training.

The emphasis will be on the limitations and factors influencing the choice of production and refining process i.e. the scientific and technological analysis of extraction processes. Outline of major competing routes of metal production from their ores. Ore treatments techniques (roasting, pressure oxidation, bio-oxidation). Thermodynamics and kinetics of hydrometallurgical processes; leaching. Cementation, precipitation, ion exchange and solvent extraction processes. Principles of electrometallurgy (electrowinning and electrorefining). Fire refining. Extraction and refining of most common commercial metals such as aluminium, copper, lead, zinc nickel, tin, gold etc.

This course is a compulsory course designed for students in the field of Metallurgical and Materials Engineering to acquire quality knowledge in the area of joining of materials especially metallic materials. However, students studying mechanical and production engineering are not exempted from the benefits offered by this course as it provides sound knowledge and a dependable background on the principle, processes and practices that governs materials joining and welding technology.

This course is designed for students in the field of Metallurgical and Materials Engineering to acquire quality knowledge in Nanotechnology. Since Nanotechnology is multidisciplinary, students studying other engineering courses can benefit from the opportunities offered by this course as it provides sound knowledge of nanotechnology. Nanotechnology pulls theories and conceptions from various disciplines: comprising engineering, physics, chemistry, biology, mathematics and computer science. It is being proclaimed as the next big technological revolution. Its use varied, ranging from traditional device physics, to molecular self assembly, to improving new substances with dimensions on the nanoscale.

This course is an elective, the course is designed primarily for students in metallurgical and materials engineering disciplines who wish to understand the science of materials: quantum theory, band and zone theory, amongst others.

The course will provide the students with the definition of powder metallurgy and also introduce them to the different powder making processes. Other stages that are involved in the production of metal powders will be studied. These stages include sizing and grading of metal powders, compaction of metal powders, sintering and finishing operations. Strong emphasis will be on the theoretical aspect of the course. Areas of application as well as economic importance in terms of investment will be considered. Advantages and the disadvantages of the process will be thought. The study will looked into the future trend for powder metallurgy process and products as well as safety in line with powder metallurgy process.

This course is designed for students in the field of Metallurgical and Materials Engineering to acquire quality knowledge in the area of design and production of metals and alloys. However, students studying mechanical and production engineering are not exempted from the benefits offered by this course as it provides sound knowledge and a dependable background on how most engineering parts are produced. In fact, the sustainability of any manufacturing industry depends on the knowledge of foundry. This is simply because most parts needed in operation and maintenance is economically produced via foundry technology. The course is nourished with practical problems and solutions that will enhance the skill of the students especially those that are willing to be self reliant in future. The course is an entrepreneurship course that avail the student the opportunity of becoming self employed after they might have graduated from the University. Topics to be covered in the course include: melting practice; casting processes; gating systems; fluidity; risering; solidification of metals/alloys; casting defects; and casting design
