The forging process developed for the Phase V universal thin section W-2Mo forging was successfully scaled up. Initial forging trials of the scaled configuration were completed with high purity cast extruded unalloyed tungsten billets having hot-cold worked and recrystallized structures. Test data indicate the superiority of starting billets of uniformly recrystallized structures. Evaluation of forgings produced demonstrates that forging quality can be controlled during scale up. Ductile-brittle transition temperature and high temperature tensile properties are reported.
