we observed that non-heat treatable al-fe-mn alloy foils exhibit an increase in strength and a decrease in elongation due to low temperature annealing treatment subsequent to cold rolling. in this presentation, we investigate the effects of alloying elements on the anneal-hardening behavior. the aluminum alloys without alloying element of fe were not hardened by low temperature annealing treatment. on the other hand, the anneal-hardening behavior was observed only in al-fe based alloys containing mn, cr, or zr. in the al-fe-mn alloy foils before and after annealing, no fine precipitate particles could be observed in tem, and no peak on the dsc curves could be observed. these results are similar to “hardening by annealing” reported on severe plastic deformation of metal.
