CRC 1153 - ORKG, Materials Science and Process Chains

How can researchers bring together knowledge scattered across multiple publications? Researchers from the Collaborative Research Center 1153 “Tailored Forming” used the ORKG to explore this question for Tailored Forming Process Chains.

Tailored forming is a manufacturing approach for producing components from different materials by combining forming and joining processes in a single process chain. Information about how a material changes with each step is scattered across multiple publications.
To combine this information and get an overview over the whole process chain, researchers first created a template to structure the knowledge. Then, they added the relevant publications in this schema. By combining the papers into a machine-actionable Comparison, they have created the basis for all further investigation. The data has since been used to create tables and visualizations.

Furthermore, the data has been queried to answer eight competency questions relevant to researchers from the field:

1. How often are which qualities of hybrid components examined in the individual steps of the Tailored Forming Process Chain?
2. Which material combinations are used for the manufacturing of hybrid components?
3. How do the steps of the Tailored Forming Process Chain affect the hardness of the cladding layer of hybrid components?
4. In which material combinations and steps of the Tailored Forming Process Chain can defects occur in hybrid components?
5. What service lives can be achieved for hybrid components in the Tailored Forming Process Chain?
6. Which manufacturing methods are used in the individual steps of the Tailored Forming Process Chain to manufacture the respective hybrid component?
7. How often are certain manufacturing methods used in total in all described Tailored Forming Process Chains?
8. Which microstructures are present in hybrid components after the steps of the Tailored Forming Process Chain?

With the data in the ORKG, each of these questions was answered using a Jupyter notebook.
Now that the structure is already established, it is easy to add new publications. Any researcher can access, add to, reproduce and reuse the data.

To learn more about the process, the answers to the competency questions and other interesting findings achieved with machine-actionable data, visit the ORKG Comparison or take a look at the publication.
