PhD Scholarship in Design of Metal Powders for 3D Printing

Technical University of Denmark, Denmark is offering PhD position in mechanical engineering. This position is available for 3 years. Applications should be sent before August 18, 2019.

DTU Mechanical Engineering, the Section for Manufacturing Engineering invites applications for a PhD position (3 years) in the field of design of metal powders for 3D printing. The Section for Manufacturing Engineering performs theoretical, numerical, and experimental research in the field of manufacturing engineering. It covers a wide range of manufacturing processes and modelling approaches, metrology at all scales, micro/nano manufacturing, and additive manufacturing. The research is based on a multidisciplinary use of process technology, materials science, solid and fluid mechanics as well as thermodynamics and heat transfer in the analysis, modelling, and development of manufacturing processes.

Additive manufacturing (AM) in the form of 3D printing has attracted much attention in recent years. However, too little focus has been devoted to the metallurgy, size and shape of the powders used in the processes. This project aims to develop new powders, based on virgin as well as recycled materials, with improved performance resulting in printed parts with more uniform and predictive properties, less residual stress and lower susceptibility to cracking than existing ones. The quality of the powders will be characterised and relations to the microstructures and properties of the printed parts will be established. The project is part of a research project titled: "Design of metal powders for 3D printing - from scrap to resource" which is funded by the Danish Council for Independent Research. The objective of the PhD project is relating the microstructure and properties of printed samples to the physical and chemical characteristics of the atomised powders. Such an analysis is expected to become a break-through as the processing parameters in AM are far from conventional and the work published in literature so far has mainly focussed on effects of the printing process (not the powder). Another important problem to be investigated by the PhD student, is the interaction between microstructural features and solutes/second phase particles. It is particularly important to develop new alloys that are insensitive to the build-up of trace elements that occur over time in recycled steels. You will be responsible for running-in of an in-house gas atomizer and carry out laboratory experiments with production of gas atomised powders and the subsequent fractioning and characterisation of powders

Candidates may apply prior to obtaining their master’s degree but cannot begin before having received it.

All interested candidates irrespective of age, gender,race, disability, religion or ethnic background are encouraged to apply.

Deadline: August 18, 2019
