Witryna25 maj 2024 · The incorporated impurities (carbon, sulfur, oxygen, chlorine) segregate toward the Sn/Cu interface during thermal aging at 200°C which induces the formation of voids and the Cu-impurity compounds (CuO and CuS 2) in the Cu 6 Sn 5 and Cu 3 Sn phase layers, severely destroying the microstructural integrity and the mechanical … 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.
