High-temperature wetting and interfacial interaction between liquid Al and TiB2 ceramic
The wetting behaviour and interfacial interactions between liquid Al and TiB2 ceramic have been studied by the sessile drop technique in the temperature range from 700 to 1400 °C. At about 800 °C, liquid Al start...

Phase separation in monotectic alloys as a route for liquid state fabrication of composite materials
The mechanism of liquid–liquid phase separation and factors determining the solid-state microstructure of monotectic alloys are discussed. The effect of the cooling rate on the phase-separated morphology is sh...

Open AccessSessile drop study of Gd–Ti monotectic alloys on ceramic substrates: phase transformations, wetting, and reactivity
Gd–Ti monotectic alloys were studied in a wide temperature range by the sessile drop technique. The eutectic and monotectic transformations in Gd–Ti alloys upon heating were in situ monitored by a high-speed a...

Preparation and phase transformations of melt-spun Al–Ge–Si brazing foils
A series of Al-Ge-Si alloys was melt spun into ribbons of about 40 μm thickness. The alloy compositions were selected so as to be suitable as filler metals with brazing temperatures <500°C. In the as-quenched ...
