Brass Cartridge Case Flaw Detection.

Abstract

It appeared in earlier work at Frankford Arsenal that an improperly annealed condition in small caliber cartridge cases could be detected by thermal imaging with liquid crystals. If applicable, this could be used to replace the 'Mercury Cracking Test' (based on ASTM Method B154-58, Mercurous Nitrate Test for Copper and Copper Alloys). This would allow eliminating mercury and spent acid from the effluent from cartridge case production lines.
