... nonuniform recrystallization and grain growth. Various approaches are available for minimizing the undesirable effects of segregation. In some forgings, the centerline is actually removed from the finished product in the form of a core bar by machine trepanning. This is permissible for some symmetrical...

... rolled solid bar stock or from heavy-wall seamless steel tubing. Larger-diameter molds can be made from forgings or hot rolled bar stock with the center trepanned or from centrifugally cast heavy-wall steel tubing. Machining allowances for castings depend on melting practices, the condition and...

... random from the product mass, so test specimens are generally taken from excess material added to the bulk for such purposes. For a casting, it may be possible to trepan sections at locations that will undergo machining at some later step. The practice of casting a small keel block for test specimens can...

... trepanning the part. The nonlinear elastic methods, including Barkhausen noise, eddy current, and ultrasonic, rely on higher-order effects of stress on the magnetic, electrical, or acoustical properties of the part. If the part is not externally constrained, then the residual-stress distribution must be...
