Zusammenfassung:The extrusion of three B-66 (Cb-5Mo-5V-1Zr) billets completed the extrusion part of the program. The processing of D-43, previously designated X-110, (Cb-10W-1Zr-0.1C) tube blanks was continued. Some of the blanks have been processed through four reductions w00 F anneals after the first and third reduction. The outside surfaces are good. The inside surfaces have been improved by in-process conditioning, but a few defects still remain. Attempts to make first reductions on the B-66 blanks resulted in cracking. The conditions that appear necessary for tube reducing the B-66, namely warm working, are beyond the scope of the present contract. Consequently, the work with B-66 was suspended, except for one piece of material which survived the first tube reduction.
