Ten tungsten materials with different impurity concentrations and different microstructures have been investigated by Auger electron spectroscopy and scanning electron microscopy with respect to their fracture behaviour. For almost all samples, both inter- and transgranular fracture are observed, and the proportion of each type varies. Due to the difference in their impurity content and grain boundary area, a large variation in the grain boundary impurities can be expected. By analysing the… 
Preprint of : Intergranular fracture of tungsten containing phosphorus impurities : A first principles investigation
In the present work we have studied the influence of phosphorus impurities on the grain boundary strength of tungsten by means of quantum mechanical calculations based on density functional theory.
Effect of Boron on Microstructure and Fracture of Sintered Ultrafine-Grained Tungsten
AbstractUltrafine-grained tungsten shows strong potential for ballistic applications because of its increased strength, and higher propensity for strain localization compared with coarse-grained
Fracture toughness evaluation of UFG tungsten foil
Abstract The fracture behaviour of pure, ultrafine grained 100 μm tungsten foil was investigated as a function of testing direction and temperature in the range from −196 °C to 800 °C. To study the

Brittle fracture of polycrystalline tungsten
A comparative study of the brittle fracture of three varieties of polycrystalline tungsten has been carried out using mainly impact tests, scanning electron microscopy and Auger spectroscopy. It
The influence of microstructure on fracture of drawn tungsten wire
The microstructures and longitudinal fracture resistances of 0.635 mm diam lamp-doped and undoped tungsten wire were examined in the as-drawn condition and after anealing at temperatures between 600
Anisotropic fracture behaviour and brittle-to-ductile transition of polycrystalline tungsten
The fracture behaviour of polycrystalline sintered and rolled tungsten rods was investigated from −150°C to 950°C by means of three-point bending tests and electron microscopy where special attention
Embrittlement of Tungsten Wires by Contaminants
TUNGSTEN in a fully recrystallized state is well known to be brittle, but in a drawn state or even after primary recrystallization1 is reasonably ductile and amenable to forming. This mechanically
Embrittlement of Tungsten and of Molybdenum
A RECENT paper from this laboratory1 described the embrittlement of tungsten wire if it be heated in atmospheres containing even traces of ammonia. This work has been extended and has revealed a
