An Assessment of Test Environments for the Stress Corrosion Cracking of Small Caliber Brass Cartridge Cases
Abstract
Non-polluting and non-toxic stress corrosion testing methods, applicable to brass cartridge cases, are evaluated as potential alternates for the mercurous nitrate method. In this assessment, rapidity and reliability of indicating stress corrosion susceptibility are important considerations. Included are: vapor tests - specimens over ammonium hydroxide, ammonium carbonate, or various organic amine liquids; solution tests - specimens immersed in ammonium hydroxide, devoid of or containing hydrogen peroxide, in amine liquids, or in Mattsson's solution. Stressed or stress-relieved specimens are employed. The results of these experiments are compared to those of the mercurous nitrate test. Specific conclusions are rendered concerning the ammonia vapor and the Mattsson test methods, and a recommendation is made concerning modifying the Mattsson test method.
