A method to eliminate stretcher-strain marking (random marking), appearing mostly in lightly strained regions, was studied in various sheets of Al-Mg alloys. Further, an aging characteristic and mechanical properties of the alloys sheets which had been subjected to the elimination method were investigated. The results obtained were as follows:
(1) Recrystallized fine grained sheets of Al-Mg alloys, which developed random marks during stretching processes, all showed yield points in stress-strain curves at tensile tests.
(2) A practical method to eliminate yielding phenomena was found. It consisted of water quenching from 350°C to 400°C.
(3) The sheets, subjected to the above treatment, did not develop significant aging.
(4) The higher the Mg content, the higher "n" values were obtained in the heat-treated sheets. The addition of Cu in the alloys inhibited grain growth. These results suggest that Al-Mg-Cu alloys with high Mg contents are suitable for forming use.
