Interfacial phenomena, nucleation and phase formation at solid/liquid interfaces

Heterogeneous nucleation in Al alloys stimulated by TiB2 inoculant: left panel - 3D view of as-cast Al-Pb monotectic alloy; right panel - EBSD image of the additively manufactured by selective laser melting Al-12Si parts without and with TiB2 additions.

Interfacial phenomena, nucleation and phase formation at solid/liquid interfaces

Wetting, interfacial reactions, nucleation and phase formation at the solid-liquid interfaces play an important role in alloy casting, fabrication of composites, and joining of ceramic parts. We investigate these phenomena by sessile-drop method and analyse the microstructure of solidified parts using XRD, SEM/EDX, computed X-ray tomography.
