Eduard Hryha

Full Professor at Materials and manufacture

Eduard Hryha is researcher in powder metallurgy and metal additive manufacturing. He is also director of CAM2 (https://www.chalmers.se/en/centres/cam2/Pages/default.aspx ) - competence centre focusing on powder-based metal additive manufacturing.

His research focuses on:
- Powder metallurgy: powder manufacturing and properties, compaction, high-performance PM steels, tailored sintering processes, sintering atmospheres, soft magnetic composites (SMC), hot isostatic pressing, synthesis, etc.
- Powder based metal additive manufacturing: relationship between powder feedstock -AM processing – properties of AM fabricated material with focus on powder bed fusion processes (laser based and electron beam) and binder jetting, powder for AM and powder degradation during AM processing, AM process development, processing gas in AM, in-situ process monitoring, quality assurance in AM, productivity in AM, etc.
- Surface analysis using advanced surface-sensitive techniques: characterization of surface composition and solid-gas interaction on the nano-level using surface-sensitive techniques as XPS (X-ray photoelectron spectroscopy) and Auger spectroscopy
- Thermal analysis: TG/DTA/DSC/DIL in inert and reducing (e.g. hydrogen) atmospheres and vacuum.
