This report describes the topographical changes that are produced as a result of the impingement of high velocity, high pressure gases upon the surface of aluminum cartridge case alloys. The principal methods of examination included scanning microscopy and optical microscopy. The results indicate that eroded surfaces can occur from either a solid metal flow or a molten metal flow. The results also show that inert organic liners are effective in reducing erosion damage of aluminum cartridge cases. Author
