Paper Title:
Mechanical Properties of W-X (X=Cu, Ag or BAg-8) Composites
  Abstract

Bend tests were performed at temperatures between 273 and 363 K for W-19vol%Cu, W-22vol%Ag and W-19vol%(BAg-8) composites. Yield and/or maximum strengths and ductility of the composite were discussed in terms of microstructure and fractography. Results are summarized as follows. (1) Almost no difference was recognized in yield strength between the composites. In contrast, a large difference was recognized in maximum strength and ductility between the composites. Maximum strength and ductility of W-Ag and W-(BAg-8) composites were generally much inferior to those of W-Cu composite. (2) Inferior mechanical properties of W-Ag composite to W-Cu composite are attributed to heterogeneous distribution of Ag-phases, whilst inferior mechanical properties of W-(BAg-8) composite to W-Cu composite are attributed to large pores at grain boundaries.
