Mechanical properties of tungsten wires after cycling deformation treatment


This article presents the influence of cycling deformation treatment executed by continuous multilateral bending with shearing on the mechanical and technological important properties of tungsten wire intended for production of spiral shapes. The mechanical properties are determined by a simple uniaxial tensile test while the technological capability is based on torsion with tension test (TT test). It is shown that the cycling deformation treatment of the wire practically does not change its mechanical parameters, but significantly increases its technological properties. The results therefore indicate an inadequacy of a simple tension test for selection (quality assessment) of tungsten wires.
