Abstract
Specimens of α brass were quenched in a very short time of 0.01∼0.04 seconds after the completion of hot-working, thus preventing the recrystallization after hot-working. We investigated those specimens with X-ray taking the Debye-Scherrer rings of Kα lines of copper. Those specimens which were worked at the so called hot-working temperature showed remarkable internal stress and grain fragmentation comparable to those of the cold-worked specimens. The effect of the degree of working on the structure of the specimens became the less, the higher the working temperature. The specimens lost its strong fiber structure and acquired a random-oriented structure by the recrystallization during air cooling after the hot-working.
