Abstract:

Correlation of behavior of the materials in firing tests and vented bomb experiments, results of mechanical property tests, and economic limitations were used to select three materials - chrome-plated CG-27, chrome-plated H22, and a cobalt base metal power alloy - for intensive evaluation. The hot extrusioncold swaging production sequence was employed in barrel manufacture. The as-swaged bore surfaces were directly chrome plated to produce a finished bore. Chrome-plated CG-27 and chrome-plated H11 barrels were made.
