Abstract

Abnormal grain growth was observed in 5056 alloy.<br>Metallographic examinations were made for the following two series of alloys.<br>Series A: Al-Mg binary system, hot and cold rolled.<br>Series B: Al-5%Mg alloys containing small amounts of Mn and/or Cr, hot and cold rolled.<br>The results obtained were as follows.<br>(1) The abnormal grain growth in 5056 alloy was closely related with Cr and/or Mn contents. The phenomenon took place at under 0.3%Cr contents and/or 0.4% of Mn contents.<br>(2) The secondary recrystallization temperature was higher and the ultimate maximum grain size was smaller with the increase in Mn and/or Cr contents.<br>(3) The abnormal coarse grains in the outer layer of the plate were discoidal; while, the grains in the middle layer remained fine.
