Abstract Scope The study of damage tolerance of tungsten wires with a diameter of 150 m is presented. Anisotropic fracture behaviour is investigated by orientation sensitive experiments performed in two principle directions. Single edge notched tension specimens, with a crack propagation direction perpendicular to drawing direction, were tested on miniaturized testing gear. For the second testing direction, where the crack propagation direction is parallel to the drawing direction, micrometre sized cantilevers were laser fabricated and tested inside of a SEM using a diamond indenter tip. The experiments were performed at RT on pure and potassium doped tungsten wires, followed by a detailed characterization of fracture surfaces. EBSD detector was used to determine the microstructure of the wire, analyse the texture and the grain size distribution. Additionally, different heat treatments (900C, 1100C, 1300C and 1500C) were performed in order to determine and compare the microstructural stability of the two investigated materials.
