Solid-state structures, highly soluble

Whereas the solubility of Cu in aluminum metal is ca. 5 wt% at temperatures in excess of 500°C, the solubility drops to ca. 0.1 wt% at room temperature. Hence, a metastable alloy is present when the high temperature alloy is rapidly quenched. Subsequent annealing will result in further strengthening similar to what we discussed for martensite. The strengthening effect is thought to occm due to the formation of Cu-rich discs (approx, diameter of 100 atoms, and thickness of ca. 4 atoms) that align themselves preferentially with selected planes of the host A1 lattice, causing coherency strains within the solid-state structure. [Pg.130]

The triaminosilane 2 is somewhat air- and moisture-sensitive but can be stored indefinitely in an inert atmosphere. Minor deviations in the elemental analysis data are due to the formation of silicon carbide and silicon nitride. It is highly soluble in common organic solvents. The solid-state structure of 2 has been determined by single-crystal X-ray analysis and shows nitrogen-hydrogen bridges. ... [Pg.233]
