抄録

It is known that mechanical strength of 6-4 brass is stronger than 65-35 or 7-3 brass, but the cold-workability is less than α brass. The author has studied on the improvement of cold-workability and other properties. It seems possible to change the structure and some properties by combined heat treatments with cold rolling.<BR>One of the effective conditions is to carry out tempering from 500°C to 600°C after 70% cold rolling following quenching at 820°C. When the rolling reduction is less than 50%, these treatments are not effective.<BR>In consequence of these treatment, 6-4 brass has more elongation in comparison with ordinaty 6-4 brass which has the same strength. It is also found that the variation of the Erichsen value is not clear, but the deep drawability and bending workability are clearly changed with the tempering temperature and time.
