Conclusions
-
1.
Short heating to 500°C of beryllium bronzes hardened and aged at 300–340°C and also aged after cold plastic deformation leads to softening as the result of reverse solution. The effects of reverse solution are caused by the dispersion of the structure and do not depend upon the nature of the precipitate phases.
-
2.
Beryllium bronze acquires resistance to reverse solution if in aging the α-solid solution decomposition occurs according to the interrupted precipitation mechanism.
-
3.
Treatment for reverse solution at 500°C with a hold of 10 sec may be used as a method of softening of beryllium bronzes in place of the traditional intermediate hardening.
