Abstract
A dispersion-strengthened material is described which comprises aluminium or aluminium alloy containing a substantially uniform dispersion of ceramic particles to confer dispersion strengthening which is inherently stable at high working temperatures, the ceramic particles having a diameter of less than 400 nm, and preferably in the range 10 nm to 100 nm. Suitable ceramic dispersoids include Al2O3, TiO2, Al3C4, ZrO2, Si3N4, SiC, SiO2.
