Researchers from the AID4GREENEST project shared their latest findings at the International Conference on Diffusion in Solids and Liquids (DSL 2026), held in Rhodes, Greece, highlighting cutting-edge work in the characterisation and development of advanced engineering materials.
Paula Alejandra Chonillo Vera, an AID4GREENEST researcher at IMDEA Materials Institute, presented her project-related research on EBSD-based microstructural characterisation and prior austenite grain reconstruction in 30CrMoNiV5-11 bainitic heat-resistant steel.
This high-strength, low-alloy bainitic steel is widely used in critical industrial applications where reliability and durability are essential. Combining high strength, toughness, fatigue resistance and excellent performance at elevated temperatures, the material is particularly suited for components operating under demanding conditions.
“Due to its excellent high-temperature creep resistance, it is widely used in components for power generation plants operating at temperatures of approximately 550-580°C,” explained Paula. “It is also more cost-effective than some alternative steels designed for the same service temperature range.”
Her research focuses on understanding the material’s microstructure through advanced electron backscatter diffraction (EBSD) techniques, providing valuable insights into the relationship between processing, microstructure and performance. Such knowledge is essential for the development of safer, more efficient and longer-lasting components for energy-intensive industries.
Paula was accompanied at the conference by fellow IMDEA Materials Institute researcher Archana Ravi, who presented her recent work on microstructural evolution during rapid solidification and thermal cycling in additive manufacturing alloys. The research was carried out within the framework of the DILAPRO Project, another European initiative in which IMDEA Materials is a partner.
The International Conference on Diffusion in Solids and Liquids brings together researchers from around the world to discuss the latest advances in diffusion phenomena, materials processing and microstructural engineering, fostering collaboration across academia and industry.
