Abstract:Recrystallization in a pure Al-1. 3 % Mn alloy containing large undeformable particles was investigated at low annealing temperature with concurrent precipitation and emphasis was put on its orientational aspect. Results revealed significant changes in microstructure and microtexture due to an inhomogeneous precipitation as compared with those at high annealing temperatures. Despite the easy nucleation at large particles,precipitation substantially suppressed the growth of grains formed there and the texture was mainly influenced by the grains formed at grain boundaries.
Key words: recrystallization; precipitation; Al-Mn alloys
