BS>The preparation of non-consumable arc melted buttons required for the Phase I study of the W-Ta-Hf ternary system was essentially completed. The majority of the specimens of the W-Ta-Re system were also prepared. Investigation of the as-cast microstructure and hardness of these alloys is near completion. The determination of the 2000 deg phase diagram isotherm was initiated and is progressing satisfactorily. Determination of workability, oxidation studies and the investigation of analytical methods were continued. (For preceding period see Ad-214471.) (auth)
