Project- Developing low-cost titanium alloys for land-based applications 

Grantee Description

Michael Oluwatosin Bodunrin is a Lecturer in the Department of Metallurgical and Materials Engineering, Federal University of Technology Akure, Ondo State, Nigeria. He is completing his Doctorate at the University of the Witwatersrand in South Africa.  His doctoral research work on the hot deformation and corrosion behaviour of low-cost titanium alloys was funded by the African Materials Science and Engineering Network, a Carnegie RISE-IAS network.   

Bodunrin has presented his research findings at several conferences and workshops and has co-authored more than 20 peer-reviewed articles in reputable academic journals. One of his review articles has been ranked as the most cited article in Elsevier’s Journal of Materials Research Technology, a Scopus indexed journal.  His current research interests include the structure-property relationship of titanium alloys and aluminum matrix composites, thermomechanical simulation and finite element modelling.

Apart from teaching, research and mentoring, Bodunrin is actively involved in science communication. His science communication article was selected as one of the best South Africa’s postgraduate science writing in 2016 by Science Today. He was also a national finalist at South Africa’s FAMELAB science communication competition in 2017.

Project- Developing low-cost titanium alloys for land-based applications 

This research aims to add value to the abundant titanium ore reserves in South Africa.

Titanium alloys have a good strength-to-weight ratio, excellent corrosion resistance and are biocompatible. However, the alloys are highly priced and this impedes their widespread applicability. The factors contributing to the high cost of titanium alloys include the use of expensive alloying elements, complex hot working process and difficult machining when forming titanium components into different shapes. 

To date, the use of inexpensive alloying elements and the optimisation of hot working parameters at laboratory testing scale have been adopted to address the high cost of titanium alloys. However, there is need to optimise the hot working and machining parameters at scales comparable with the commercial production processes.

Therefore, this research will focus extensively on the optimisation of the hot working and machining parameters of the low-cost alloys at scales comparable with commercial production processes. This will be achieved through the combination of finite element modelling, experimental validation and advanced characterisation technique. 

The bulk of the research work will be conducted mainly at the host university, University of the Witwatersrand while the advanced characterisation will be carried out at Oxford University in the UK. 

The knowledge obtained from this work will be useful for developing the low-cost alloys in commercial quantity.
