Project

Additive manufacturing (AM) offers the capacity to produce near net shaped complex components. Apart from some of the most used materials for AM technology development, e.g. titanium, steels, Inconel, and AlSiMg, additive manufacturing of aluminium alloys using wire based process has recently gained attention from the industries and researchers.

High strength aluminium alloys made by the wire + arc additive manufacturing (WAAM) process will be the subject of study in this project, which have found applications in the aerospace and automotive sectors. However, AM process may induced defects, e.g. porosity, lack of fusion, and keyholes, which can affect the mechanical properties and structural integrity performance. For safety critical structural components, this must be investigated and criticality of defect levels must be set.

Aim is to investigate the effect of defects in WAAM processed aluminium alloys. Main objectives are to conduct experimental testing and computational modelling, to characterise the defect morphology, and to study the defect criticality and impact on fatigue strength of safety critical structures.

Benefits

The successful candidate will receive comprehensive research training including technical, personal and professional skills.

All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College and Centre for Research Capability and Development, which provides support with high-quality training and career development activities.
