Conference Presentation
Our graduate student Ecem Süt, under the supervision of Assist. Prof. Dr. Yasemin Yıldıran Avcu, presented her research at the MEETCON – Global 2nd International Scientific Research Congress, held in Madrid, Spain, between May 23–30, 2026.
New publication in Journal of Materials Science & Technology!
Our article entitled “Quantifying carbide size effects on strain localization and fracture mechanisms in martensitic steels” has been published in Journal of Materials Science & Technology.
This study quantitatively investigates how carbide size affects local strain accumulation and fracture mechanisms in martensitic steels by combining high-resolution digital image correlation, FIB sectioning, and crystal plasticity modelling. The findings highlight carbide size as a critical microstructural parameter governing strain localization, damage evolution, and fracture behaviour in martensitic steels.

About Us
We investigate microstructure–mechanics relationships in advanced alloys and composites, with a strong focus on severe plastic deformation (e.g., ECAP) and surface engineering (e.g., shot peening and related mechanical surface treatments). Using HRDIC-enabled in situ SEM together with correlative characterisation (e.g., EBSD, TEM/HRTEM, and X-ray CT), we uncover how hierarchical and hetero-structured architectures govern strengthening, strain heterogeneity, and damage resistance at the microstructural scale.
We translate these insights into advanced materials developed via powder metallurgy (PM), additive manufacturing (AM), and SPD-based processing for failure-critical applications (e.g., biomedical implants, aerospace structures, and energy/transport components).
