Abstract:

A method for testing the behavior of thin tungsten wires at bending deformation is described. All tungsten wires show, within a narrow temperature range, the transition from brittle to ductile behavior. For wires with a fiber texture this transition temperature T sub e is below zero C for recrystallized wires, at 150-400C. Long-crystalline wires have a lower T sub e than the short- crystalline ones. The position T sub e is determined by the form of the fracture transcrystalline resp. intercrystalline.
