Judit Svidró works as a Post-doc researcher at the Department of Materials and Manufacturing at Jönköping University School of Engineering.
She grew up in a city that’s the history of iron and steel industry extends as far back as the 18th century. The majority of the population was working in the steel mill, the foundry or the processing plant, so at least one of your relatives certainly had personal experience in iron and steelmaking. It was a part of our lives I would say. However, I understood the function of all the plants only later, during my undergraduate studies. The university also has a long-standing historical tradition in metallurgy and all my professors were so passionate about metal casting, that it rubbed off on me.
Her research covers the topic of molding materials used in metal casting. My interests include the thermal and thermophysical properties of foundry sands and moulding mixtures, reclamation processes and metal-mold reactions. Judit is now involved “New Generation of Foundry Sands”, co-funded by the Regional Development Council of Jönköping County. This project aims to make the casting manufacturing process more sustainable by the reduction of costs and environmental load through the development of silica sand with improved thermal properties.
She is also working in the project “LeanCast”, funded by Knowledge Foundation, which focuses on how to enable and control a lean and sustainable design and production of cast iron components.
Judit believes that additive manufacturing is gathering ground, penetrating into markets and product families that are traditionally covered by metal casting. The automotive industry is still the driving force when it comes to metal casting, so the further development of complex structural parts and lightweight components is always on the table, she said.
Moreover, market understanding, innovation requires deep technical knowledge and dialogue between actors working in industry and research. Her impression is, that foundries are increasingly investing in R&D and interested in taking part in research projects targeting even more fundamental topics. Engagement in competence development also became important and these tendencies are very advantageous since this approach provides continuous improvement in the world of technology.
Toni Bogdanoff is a PhD student and lecturer in Jönköping University, School of Engineering. He obtained Master degree in product development, specialization in materials and manufacturing. Toni is currently researching in the field of fatigue properties of aluminum cast alloys in CIC projects.
We are investigating the impact of microstructural features, chemical compositions, shapes and sizes of phases and their interactions with the matrix when exposed to several loading conditions such as; tension-compression, rotation bending, pure rotation, and pure bending, Toni said.
His interest for casting developed at a young age. The first time I got in contact with metal casting was when I created tin soldiers as a child. However, after making soldiers it took a while. During my bachelor thesis at Jönköping University, 2009 got interested in metal casting. The addition of alloying elements to Aluminium-Silicon alloys change the mechanical properties and significantly modify morphological shape of phases was a nucleation point to interest.
Toni is positive when he thinks about the future of metal casting. He says
- The growing demands from laws and legislation inspire researchers to develop new materials. The importance to reduce weight in the automotive and implementation of electrical cars will increase the usage of light materials. Moreover, new alloys will be developed with superior properties.
