Dealloying of an Au-based amorphous alloy [PDF]
Intermetallics, 2010 Abstract The dealloying behaviour of Au 42 Cu 29 Ti 8 Si 21 and Au 44 Cu 31 Ti 4 Si 21 amorphous (wheel-side) and partially crystalline (air-side) ribbons was investigated using potentiostatic and galvanostatic etching. The resulting microstructures are: i) on the wheel-side homogeneous porosity with size from tens of nanometers to less than 1 μm ...

Amorphous Phase in Palladium—Silicon Alloys [PDF]
, 1965 By rapid cooling from the melt, an amorphous phase has been obtained in palladium—silicon alloys containing 15 to 23 at.% Si. This phase is stable at room temperature and crystallization cannot be detected after one month at 250°C.

Molecular beam epitaxy of highly mismatched N-rich GaNSb and InNAs alloys [PDF]
, 2013 GaN materials alloyed with group V anions form the so-called highly mismatched alloys (HMAs). Recently, the authors succeeded in growing N-rich GaNAs and GaNBi alloys over a large composition range by plasma-assisted molecular beam epitaxy (PA-MBE). Here,
