Abstract: The weapon barrel comprises a liner and at least one jacket tube. The liner is made of a highly wear-resistant material, like a cobalt or nickel base alloy, and the jacket tube is made of a tough alloy, like steel. In the manufacturing process the liner material is packed into the jacket tube in the form of a powdery material which may be pre-pressed or pre-sintered. The packing is arranged such as to leave a central free space in the jacket tube, and the jacket tube may be surrounded by an encapsulating tube. The jacket tube or the encapsulating tube is closed either before or after evacuation, and the closed tube arrangement is subjected to a combined heat and pressure treatment at temperatures of at least 900.degree. C., but below the melting point of the relevant materials and at pressures of at least 900 bar. The compound body thus obtained is formed with a full-area metallic bond between the liner and the jacket tube.
