Ontology-based representation of process-structure-property relationships of metals for use in additive manufacturing

Research question

Society is currently facing tremendous technology transitions due to sustainability challenges and digitalization. This will have a significant impact on how we produce, use and hopefully recycle materials. Unfortunately, there is a risk of partly losing decades of engineering experience in this transition if one cannot adapt the existing knowledge to the new framework for how materials are designed, manufactured, and used. This existing knowledge can take different forms, such as experiences encoded in materials data generated in extensive and costly experimental test campaigns, but also field experience collected from components subjected to many years of service. However, by using smart ontology-based representations of the process-structure-property relationships of the materials we can turn the risk to an opportunity, where these transitions can reshape and expand the knowledge base and approaches used within the field of materials engineering.

Sustainability aspects

An ontology-based representation of process-structure-property relationships of metals will enable a faster implementation of new alloys and manufacturing techniques, such as additive manufacturing. This, in turn, will speed up the transition a more sustainably manufacturing industry
