İdris Gökalp is a Research Assistant in the Department of Metallurgical and Materials Engineering at Kocaeli University and a PhD student working on powder metallurgy, advanced manufacturing, and structural materials. His research focuses on titanium- and magnesium-based systems, nickel-based superalloys, and functionally graded composites, with emphasis on microstructural characterisation, mechanical behaviour, tribology, corrosion, and surface-related performance. His doctoral research investigates carbon-particle-reinforced titanium matrix composites produced via powder metallurgy.
Research Areas : Powder metallurgy, additive manufacturing, Ti/Mg alloys, graded composites
Core Methods : SEM, XRD, wear, corrosion, fatigue, nanoindentation, heat treatment
Research Interests
- Powder metallurgy and pressure-assisted sintering
