Improvement of Additive Manufacturing Processability of Alloys and Ceramics

Project opportunity

This Earmarked Scholarship project is aligned with a recently awarded Category 1 research grant. It offers you the opportunity to work with leading researchers and contribute to large projects of national significance.

Additive manufacturing (AM, which is commonly called 3D printing) is booming. But, the current engineering alloys that can be additively manufactured (AMed) are still limited (the number of reported alloys are around 50, compared with more than 65000 commercial alloys). This implies that most commercial engineering alloys have low AM processability or 3D printability (here we define the AM processability or 3D printability as the ability of alloys that can be processed/printed through AM without failure, cracking and unacceptable level of defects, such as porosity). Hence, this proposed project aims to develop practical and effective technologies to improve the AM processability of engineering materials that are currently hard to or even cannot be processed/fabricated via AM. Such materials include intermetallic alloys, ceramics, most superalloys and copper alloys, the majority of tool and high ultrahigh strength steels, high strength aluminium alloys, and some titanium alloys. The development is based on the current understanding of factors that govern the quality of AM components and of the causes for low AM processability of these types of alloys. The most promising approach to improve the processability is grain refinement that can be achieved during solidification of the melt pools. The research solves one of the most critical problems associated with AM and the outcomes not only can improve the properties of AMed engineering components, but also will widen the applications of this advanced manufacturing technology.
