A Study of the Diffusion Zone between Ta-10W Tantalum Alloy and 4150 Steel
Abstract
Because of the erosive conditions to which barrel materials are subjected during the rapid firing of guns, materials for barrels had to be improved. One such improvement involved the lining of the bore of an AISI 4150 steel barrel with a tantalum alloy (Ta-10W). The Ta-10W alloy liner and the 4150 steel were coextruded at 1900 degrees F to form a multilayer gun tube. The extrusion produced a satisfactory bond, mechanical and metallurgical in nature, between the steel and refractory alloy liner. Although detrimental effects during test firing cannot be attributed to the diffusion zone, this zone could be a potential trouble area. Consequently, information pertaining to the diffusion zone was desirable.
