Three Mo 0.5 Ti ingots were processed to sheet bar by extrusion, forging, and rolling with good yields. Plasticities of Mo 0.5 Ti and TZM ingot structures were determined from 2400 to 4000 F. Minimum plasticity was found in the range of 3000 to 3400 F. An outline of phase II sheet rolling development is presented. This phase will consider the effect of the following process variables on 0.060 in. Mo alloy sheet 1 surface contamination, 2 transition temperature and room temperature tensile properties, 3 elevated temperature tests, 4 chemical homogeneity and impurity level, 5 laminations, 6 surface imperfections, 7 dimensional tolerance, and 8 inert atmosphere fabrication.
