Witryna(DKI A 4964) Age hardening of a Cu-Ni alloy (84.5% Cu, 7.5% Ni, 8% Sn) [7] Silicon improves the castability of casting alloys and at the same time acts as deoxidant. In the Cu-Ni system, the solubility of silicon increases with nickel content. Up to the solubility limit, increasing silicon contents raise strength and reduce ductility. Witryna1 sty 2011 · By means of x-ray photoelectron spectroscopy, together with first-principles calculations of electronic spectra, it was found 21 that the germanium impurity in Sn 2 P 2 S 6 improves the ...

Witryna24 kwi 2024 · Since the impurity incorporation in the Sn is negligible, voids hardly form at the Sn side. As a result, no ribbon-like structure was observed after thermal aging at 150 °C for 600 h. Detailed discussion of the dominant diffusion of Sn at 200 °C and the effect of temperature on the ribbon-like structure can be found in . Witryna1 sty 2024 · Effect of impurity elements on the tin iodide perovskite have been investigated using first-principles calculations. • Y impurity placed at a B site decrease E form to −0.05 eV/atom and renders the perovskite structure more stable.. The Y–I covalent bonding around E = −4 eV is relatively strong when a Y is placed at a B site. ...
