A1-base alloy having excellent high-temperature strength

摘要

An Al-base alloy prepared by hot-working a mixture of an Al alloy powder and dan Ni powder to join the powders and having a structure wherein Ni-Al intermetallic compounds are dispersed. The powder mixture can be hot-worked in the solid-phase temperature range, liquid phase temperature range or solid-liquid phase mixture temperature range of the Al alloy. A dispersion strengthening powder can be further admixed with the mixture of Al alloy powder and Ni powder.
