Conclusions
-
1.
The plasticity of brass LMtsZh 55-3-1 at high temperatures depends on the original condition.
-
2.
Quenching sharply reduces the plasticity when the brass is straightened in the heated condition.
-
3.
To prevent the negative effect of quenching before straightening, the propeller must be annealed in a furnace or the section of the blade must be annealed.
