The effect of tungsten on the mechanical properties of tantalum

Article Abstract:

Research was conducted to examine the mechanical property of Ta and Ta-W alloys. Results demonstrate that the additions of tungsten to tantalum lead to an increase in the rate of work hardening and drive the microstructure that evolves during deformation to change from one wherein the dislocations are in a cell structure to one which consists primarily of dislocation tangles. The yield strength of tantalum also increased by the additions of tungsten.

Integration of basic materials research into the design of cast components by a multi-scale methodology

Article Abstract:

Research suggests that local deformations in the design of a structural component can be studied by considering the experimental data analyzed at different levels as shown by the design of a cast automotive control arm. Data show that such knowledge will aid determining the length necessary for refining microstructures or develop new materials.
