Abstract

The AMMRC ballistic compressor is described as an instrument capable of adiabatically compressing gases to temperatures of several thousand Kelvins and pressures of several thousand atmospheres for a time of a fraction of a millisecond. Problems of measuring the gas conditions and its equations of state are discussed. Application to gun barrel erosion/corrosion is discussed through the example of various nitrogen/argon test gas experiments on 4340 steel. An interesting feature of an apparent melt and redeposit process in the formation of carbon containing nodules on the surface.
