HYDROGEN ABSORPTION BY Ti–Zr–Ni-BASED ALLOYS

attracted a lot of attention for hydrogen-storage appli-cations. Much of the research has concentrated on Ti- and quasicrystalline samples through the rapid solidification of a molten alloy on a cold spinning wheel made of copper. The cooling rate of the process has also an 8-bar over-pressure of hydrogen. The furnace was heated up to ...<<more>>

3D printing high-quality parts in aluminum alloy - GrabCAD

Only alloy’s sintering temperature limits the furnace temperature. Such drying of the powders eliminates the water adsorbed at their surface, but doesn’t decompose the hydroxides, so it does not allow to eliminate hydrogen porosity completely, unless the powder are dried in vacuum at higher temperatures (~300°C)....<<more>>

Almex - Products - Z-MET? Molten Aluminum Analyzer

The Z-MET? technique is based on the fact that, during solidification of the molten alloy under vacuum, the impurities behave in a definite manner. The solubility of hydrogen in the solidified metal is 20 times lower than its solubility in the molten metal....<<more>>
