Motivation

Spatiotemporal microstructure data are the key results of continuum full-field and atomic-scale computer simulations, as well as cutting-edge diffraction microscopy experiments. Typically represented as voxel, point, line, or finite-element meshes, these data cover a variety of materials information, such as the spatial distribution of crystal defects and their correlation with three-dimensional field quantities like temperature, mechanical stress and strain, or concentration fields of chemical species. In addition, the large variety of computer codes within the MSE community, limits interoperability and repurposeability when handshaking between different microstructure modeling tools. Here, we aim to implement an infrastructure that enables users to assess the time evolution of microstructures in correlation with field data across different length and time scales in a code-agnostic representation as FAIR digital objects that can complement or replace existing code-specific outputs. Proof-of-concept workflows are developed, which exemplify how such descriptions and ontology connections can be exported from existing MSE simulation tools, connecting full-field microstructure simulation models and atomistic modeling with property prediction tools and experimental data.

Overview

Main requirements:
- FAIR data schema for microstructures, including meta data and semantic meaning of all items
- Focus on the integration of existing open-source tools within workflows mimicking materials processing routes
- Parsers for common commercial tools will be made available
- Ready-to-use open-access demonstrators that can be adapted to individual user requirements 
Main Task Area: TA-WLE
Other related Task Areas: TA-MDI, TA-SAI
Possible connections within NFDI: NFDI4Ing, FAIRmat
Material/Data
- Spatiotemporal point/voxel data of phases and crystal orientations
- Tensorial or scalar field data from experiments or computer simulations of microstructure evolution at the microscopic and atomic scale.
Main Success Scenario: The user can characterize the geometrical arrangement of phases and grains in the material and employ flexible workflows to describe the evolution of microstructures during typical materials processing routes. This is achieved by flexibly exchanging spatiotemporal data between simulation tools for materials processing and property prediction from atomistic to microstructural length scales. 
Added value for the MatWerk community: A semantic description of microstructural features like phases, grains, grain boundaries and precipitates in form of an FDO employing a widely accepted data schema. This enables users to identify characteristic features of microstructures and their time evolution agnostic of specific data formats or implementations in a simulation code and to predict mechanical properties along typical materials processing routes.

Exemplary Case Studies

TA-WLE

  • Focus on implementing workflows that connect different simulation tools along typical materials processing routes based on code-agnostic representations of microstructures that can be flexibly exchanged between codes.
  • PP14 employs its personnel to formulate semantic data schemas and to implement demonstrator workflows for numerical modeling of microstructure evolution and property prediction along materials processing routes.
  • PP13 and PP17 contribute full 3D data of microstructures and require representations of microstructures as FAIR digital objects.
  • PP06 and PP21 contribute atomistic data of defects and require a general data schema for microstructures to transport the atomistic information onto higher length scales.

Goals

  • Semantic description and FAIR representation of spatiotemporal microstructure data, including metadata and meaningful ontologies for phases, grains, and defects.
  • Code-agnostic infrastructure to assess microstructure evolution across different length and time scales, enabling interoperability between simulation codes and experimental data.
  • Flexible workflows that connect continuum-scale and atomistic models with property prediction tools and experimental validation.
  • Ready-to-use open-access demonstrators for workflows and schemas that can be adapted to specific materials processing routes.
  • Integration of parsers and open-source tools to extract, transform, and exchange spatial and temporal microstructure information between simulation and experimental formats.
