Abstract : Three alloys consisting of 10, 25, and 50 wt-% Mo in W were evaluated at 2500 to 4400 F to determine their tensile properties. Results showed the 10 and 25 wt-% alloys have higher tensile strength than unalloyed W at 2500 and 3000 F and equivalent strength to about 3500 F. The 50 wt-% alloy has strength equivalent to unalloyed W from 2500 to 3200 F. Unalloyed W has higher strength than the alloys above 3500 F. The results of stress-rupture tests for the 50 wt-% alloy are presented for the temperature range oof 2500 to 3500 F in the as-worked and fully annealed conditions. (Author)
