Abstract:
The HEC technique was used to consolidate several precursors of refractory nanostructural tungsten-silver (W-Ag) composites into cylindrical billets. Consolidated to near theoretical density below and over the melting temperature of silver (940 - 1050°C), several compositions including a nanoscale W phase (100 nm) and a coarse matrix phase of Ag were tested. All of the tests had loading intensities of around 10GPa. High densities, excellent integrity, and outstanding electrical characteristics were achieved by consolidating nanostructural W-based composites using a combination of high temperatures and two- stage explosive densification methods. The value of the consolidation temperature and the diameter of the consolidated particle determine the structure and property of the samples. Samples without cracking, with a high density value, and uniform distribution of the two phases were produced for W-Ag based composites by applying high heat and consolidating precursors to the me
