| Abstract: | Microstructural characterisation and room temperature tensile testing were performed on a series of tungsten heavy alloys extruded at various temperatures. Ultimate tensile strength of the alloys increased with increasing extrusion ratio and with decreasing extrusion temperature down to 600°C. Fracture surface observations indicated that the tensile strength correlated with the tungsten cleavage failure mode. The matrix could inhibit the propagation of cracks initiated in the tungsten particles.MST/3384 |
