The Properties Of Cold Rolled - Stress Relief Annealed 70-30 Cartridge Brass, Robert F. Hartmann

Professional Degree Theses

"Because of the possible commercial application of the proposed treatment of 70-30 brass, this work was undertaken. In addition, the data resulting from this work will result in a better understanding of the treatment of brass.

The objectives of this work were as follows:

1. Determine if higher strength and better spring properties can be realized from a process for commercial 70-30 cartridge brass wherein the regular recrystallizing anneals between rolling reductions are replaced by stress relief anneals.
2. Determine if it is possible, using the above process, to produce essentially fully recrystallized metal with an average grain size below that usually …
