ABSTRACT:
The present invention provides a gun capable of operating at relatively higher temperatures. The barrel of the gun is made up of at least two layers. The inner layer is of a refractory material which may be a metal refractory or a non-metal refractory. The liner is bonded to an outer jacket material formed of an alloy of nickel, aluminum and molybdenum. The coefficient of expansion of the liner and of the jacket are relatively low so that the gun does not expand extensively when heated by intensive use. The jacket metal is of higher strength at elevated temperature than is the conventional gun barrel steel.
