   Abstract : The objective of the present investigation was to explore the mechanism of activated recrystallization of heavily drawn doped (non-sag) tungsten wire material. The recrystallization can be induced at low temperatures by the presence of some metals, such as palladium, nickel, iron and others, on the wire surface, which is important as it can seriously deteriorate the mechanical properties of non-sag tungsten wires, when the wires serve as reinforcement material in metal matrix composites.
