The Application of the Avitzur Upper Bound Equation to Tungsten Wire Drawing and its Use in Die-Line Design
The die line used in the drawing of tungsten wire has evolved, as is the case for most materials, through a trial and error process. No known attempts have been made to pattern the die line to the drawing characteristics of tungsten or to its mechanical properties. It was the purpose of this study to measure the force required for the drawing of tungsten wire and from those measurements and from the tensile properties, determine what an ideal die line should be.
