Mechanical Engineering Post Graduate Presentation held on the 7th June 2016

The Mechanical Engineering department post graduate presentations were held on the 7th June 2016 where a total of five presentations were made. Members of staff and students in the department were in attendance to offer the much needed support in terms of suggestions and ideas.
The first presentation was on the “Characterization of Fatigue Properties of Secondary Cast Aluminium Silicon Alloys for Cylinder Head Applications” by Gaudence Nyarirazena.The main objective of her research is to study fatigue properties of recycled Al-Si.
