... and coalesced during service. Consideration of the manufacturing process suggested that the cracks were the result of overheating of the kingpin blanks prior to forging, which was exacerbated during forging by deformation heating in the highly-strained region. This view was supported by results of two types...

... in understanding both necking and splitting. Splits typically open between 0 and 45° to the direction of load application, but this is complicated by complex blank and part shapes, die process, and metal flow. Splits are not found on critical radii but instead can be seen at the tangent point between the radii...
