Abstract : A composite gun tube having a liner prestressed in compression by a surrounding cylinder formed of an appropriate Nitinol alloy. A first alternative construction utilizes Nitinol in filamentary form wrapped around the liner. A second alternative construction utilizes filamentary Nitinol embedded in the liner material. In all cases, the Nitinol is formulated so that the critical transition temperature is below that of any environment which the gun tube might encounter.
