Description

Many engineering applications require a combination of material properties that cannot be accommodated by a monolithic material, often referred to as the Multiple Functionality Challenge. Simultaneous fabrication of more than one material in a single geometry while maintaining its structural stability and delivering functionality is hurdle for most conventional materials processing routes. When using metallic alloys, one often has to compromise between strength and ductility as most strengthening mechanisms hamper dislocation movement and plastic shaping capabilities. Powder metallurgical (PM) processing routes provide the potential to create multi-materials and functionally graded materials (FGMs) as a local compositional and concomitant property gradient can be created. Compared to conventional casting and additive manufacturing (AM), however, PM processing routes often suffer from limited near-net shaping capabilities, often requiring extensive and costly post machining. The latter, hereafter, will be referred to as the Near-net Shaping Challenge. The objective of the joint PhD proposal is to develop and demonstrate the capabilities of novel PM processing routes, combining the layer-by-layer feature of AM and pulsed electric current sintering, allowing to fabricate near-net shape components that incorporate multiple materials, addressing the near-net shaping and multiple functionality challenge.

Skills required

We are seeking a highly motivated candidate holding a Master’s degree (or equivalent) in Materials Science and Engineering or Mechanical Engineering to join our international research teams. Experience in powder metallurgy processing and/or electron microscopy would be considered a strong asset. Good communication skills in English are required. A general interest in combining numerical simulations with experimental processing and characterisation is required.
