Goals

To develop an EMMO-based domain ontology covering relevant aspects of metallic microstructures and connect it to process and characterization ontologies.

The aim for the microstructure Domain Ontology is the provide a common representational language for describing metallic microstructures including related aspects needed to support connecting microstructure characterisation to data processing and through-scale and through process modelling. It will relate microstructure, material and properties providing a common way to connect a state to external conditions, like temperature, volume/shape and pressure (essential for describing a process).

A microstructure is defined as a “state” of a material from which properties can be extracted and which can be altered by “processes”. The ontology will include both a statistical and a geometrical view or “perspective” of a microstructure and will provide means to semantically support conversion between these perspectives.

The Microstructure Domain Ontology is developed on GitHub and made public available under a creative commons license (CC-BY 4.0).

Objectives and planned outcomes

• Develop microstructure ontology as a hierarchical set of modules focusing on different aspect of the ontology.
• Create periodic releases of the ontology.
• Coordinate the development with other related EMMO-based domain ontologies, like the crystallography, atomistic and characterisation domain ontologies to ensure that they easily can be used together.

 Output so far

A first release of the ontology is available on GitHub: https://github.com/emmo-repo/domain-microstructure/tree/master

Associated research projects

• SFI PhysMet – Centre for Sustainable and Competitive Metallurgical and Manufacturing Industry is a newly funded Norwegian centre for research-based innovation lasting from 2020 to 2028. The aim is to accelerate the transformation of the national metallurgical and manufacturing industry towards more sustainable and cost-efficient production and future material products, solutions, and improved processing methods. To integrate models and tools, an ontology dedicated to metallic alloys microstructure and properties will be developed.
