Zusammenfassung:A treatment process for a composite comprising a matrix of a precipitation hardenable aluminium alloy and a particulate or short fibre ceramic reinforcement, which comprises a hot and/or cold working step and a subsequent solution treating step; characterised in that, after the hot and/or cold working step and before the solution treating step, a controlled heating step is applied in which the composite is raised from ambient temperature to a temperature of from 250 to 450 DEG C, the rate of temperature increase being less than 1000 DEG C per hour.
