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...

Comparison of the annealing behavior of thin Ta films deposited onto Si and SiO₂ substrates

Structural changes at annealing temperatures (T _an) of 500–1,100°C were investigated for thin Ta films which were sputter-deposited onto pure Si substrates and onto thermally oxidized Si. In the as-deposited stat...

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 ...
