Recrystallization behaviour of cold rolled aluminium from cast strips

Abstract

This paper revises the literature on the problems in recrystallization of cold rolled cast strips. The phenomenon of the precipitation previous or simultaneous to recrystallization, that may affect the nucleation of the recrystallization, is explained. The use of TTT (Time, Temperature, Transformation) curves to obtain the critical time and temperature without cutting the nose of the precipitation zone are examined for Al-Mn alloys it is also explained the obtainment of CTT (Concentration, Time, Temperature) curves and "grain size diagrams" on the basis of heating rate and Mn in solid solution obtainment.
