Alloys strengthened by dispersion of particles of a metal and an intermetallic compound and a process for producing such alloys

摘要

A matrix of an Al-Ni base alloy or an Al-Si-Cu base alloy is strengthened by dispersion of particles of Ni, Si or at least one intermetallic compound selected from among AlNi, Al.sub.3 Ni, Al.sub.3 Ni. sub.2 and AlNi.sub.3.
