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.

Short Term Oxidation of a Ti-46Al-8Nb Alloy at 700°C in Air [PDF]
, 2010 Thermogravimetry was used to study the oxidation behaviour of a lamellar Ti46Al8Nb alloy during holding at 700°C in synthetic air. A parabolic plot of the oxidation kinetics shows three different regimes over the total duration (50 h) of the tests ...
