Conclusions
-
1.
A reduction in the hardening temperature of BrB2 bronze from 780 to 720°C makes it possible to increase the service life by more than 1.5 times as the result of grain refinement.
-
2.
The small decrease in tensile strength after low temperature hardening has practically no influence on the hysteresis of bellows.
