Abstract : The manufacturing technology required to fabricate armor covers for critical aircraft components for protection against caliber .30APM2 projectiles was established for heat-treatable dual-hardness steel. Methods of cutting, machining, welding, bending, and roll forming were investigated, as well as the effects of heat treatment on distortion. Also established were the techniques required to fabricate seamless dual-hardness steel cylinders, which were produced in various sizes by coextrusion. (Author)
