It has been known that recrystallization of metals can be accelerated by a combined effect of high purity and a heavy deformation. There is an increasing interest in deformation and recrystallization behaviors of high purity aluminum, because of the sensitivity of its recrystallization temperature to impurities. Room temperature recrystallization of high purity aluminum is a typical example of this sensitivity and has been found and displayed in an earlier work. This result has been thought to occur statically, because aluminum was only known to undergo dynamic recovery (DRV) as a restoration mechanism due to a high stacking fault energy. However, some recent studies suggested the occurrence of dynamic recrystallization (DRX) in room temperature compression tests of 99.999 pct aluminum. Thus, the restoration mechanism of 99.999 pct aluminum during deformation is in dispute. The purpose of this study is to clarify whether or not DRX can occur in 99.999 pct aluminum that is subjected to plastic deformation at room temperature.
