Developing the next generation titanium alloys for additive manufacturing

The rise of 3D printing creates unique opportunities for Australian manufacturers to participate in high-value global supply chains. However, the lack of development in high-quality printable materials is stopping manufacturers from accessing the full potential of 3D printing. This project aims to develop a design strategy for the next generation of titanium metals designed for 3D printing. This project expects to improve the functionality of 3D-printed metals with qualities that go beyond the most demanding industry acceptance criteria. 

This PhD project seeks to develop a series of new titanium alloys that when produced by additive manufacturing (Laser Powder Bed Fusion and/or Wire Direct Energy Deposition) will have mechanical behaviour that exceeds the requirements of wrought Ti-6Al-4V products. The project will start with a blank canvas and will develop new solutions to meet the needs of key industrial applications.

The successful applicant will work with a team of experienced researchers and develop expertise in titanium metallurgy and alloy design, additive manufacturing and materials characterisation techniques including advanced electron microscopy. The successful applicant will also have the opportunity to develop skills and experience in working with the team as a paid tutor (in addition to the stipend) in mechanical and materials engineering courses within the School of Mechanical and Mining Engineering.

The successful applicant will join the School of Mechanical and Mining Engineering and have access to the facilities within the Centre for Advanced Materials Processing and Manufacturing (AMPAM). The successful applicant will leverage the solidification facilities available including melting facilities and 3D printing facilities (SLM solutions and AML3D Arcemy machines), mechanical characterisation equipment (for tensile, hardness etc.), metallographic preparation equipment and UQ’s Centre for Electron Microscopy and Microanalysis fully equipment with state-of-the-art facilities.
