For Holger, the summer meant continuing the development of AI-based image analysis for steel microstructures. His work included evaluating software, building an image library, developing a Standard Operating Procedure and training AI models for grain size measurement in both stainless steel and carbon steel. Holger's summer project also built upon a recently completed bachelor's thesis in AI-based image analysis together with fellow KTH student Anton Nilsson. The thesis explored how AI can support the analysis of steel microstructures and the results showed promising agreement with traditional measurement methods.
George focused on improving methods for grain size measurement by evaluating different parameters throughout the sample preparation process. He also carried out corrosion testing according to ASTM G48 and investigated the Critical Pitting Temperature (CPT) of different steel grades.
Student collaborations
Their projects are good examples of how students can contribute to real development work in our R&D Laboratory, where materials science, laboratory testing, digitalization and AI come together. The laboratory continuously works with method development, advanced materials characterization and evaluation of new technologies to support future product and process development.
-These type of student collaborations are important to Suzuki Garphyttan because students bring new perspectives, curiosity and fresh ideas into the laboratory. At the same time, they gain experience from real industrial challenges. For us, student collaborations are an important way to build future competence and strengthen our relationship with universities and future engineers, says Dan Larsson, Manager Laboratory & Supplier Quality Assurance
Student collaborations are an important part of Suzuki Garphyttan's long-term commitment to innovation and competence development. Through bachelor's theses, master's theses, internships and summer jobs, students gain hands-on experience while contributing to ongoing development projects.
Holger and George-Lee both found the summer highly rewarding, gaining practical experience and a deeper understanding of materials science. They also appreciated the welcoming, family-like atmosphere – including the Friday fika. Holger first met Suzuki Garphyttan at Hindersmässan in Örebro, while George got to know the company through activities at KTH. George also knew Holger, who recommended Suzuki Garphyttan as a great place to work. Now it’s time to head back to their studies. George returns to KTH for his fourth year, while Holger is heading to Japan to begin his master’s studies at Tohoku University in Sendai.
