A repeated plastic working process has been applied some Al-Ti base alloys to obtain a fine dispersion of the Al_3Ti second phase particles which always coarsen in the usual process. The process used in this study is called ECAP (Equal Channel Angular Pressing), where the metal is extruded perpendicular to the pressing direction and the reduction per cycle is approximately unity in true strain. The coarse dispersion of the Al_3Ti particles became successfully refined as the cycle of the process was increased. resulting in an increase in the yield strength. The amount of strength increment was enlarged by the addition of Cu or Mg that causes solid solution hardening in aluminum.
