... wire diameter ( Fig. 2 ). The origin of the fracture was at a subsurface void that had a triangular-shaped cross section ( Fig. 3 ). The void was associated with a drawing defect, probably produced by a scratch in the die. The fatigue striation spacing was very fine, even near the overload portion...

... 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 and draw wall...

... in the die and eliminate deep-drawing applications. Lead is soluble in β-brass up to 2%, which allows hot working of alloys such as Cu-40%Zn brass. By contrast, 0.1% Pb in an α-brass (Cu-30Zn) will result in hot cracking at forging temperatures. Insoluble lead can become liquid at forging temperatures...

... occurring. It seems probable that the explanation of this lies in the fact that when the wire passes through the die the preponderating stress is a compressive one, whilst the pull during drawing is, in general, only a fraction of the ultimate tensile strength of the wire. Failure in service was, of course...
