COLUMBIUM $sub 4$$H$$sub 4$ SECTION PROGRAM. PHASE I. EXTRUSION. PHASE II. DRAWLING. Interim Report II, October 1, 1963-January 1, 1964

Technical Report ·
OSTI ID:4115075

The development of the extrusion process for D-43 (Nb-10W-1Zr--0.1C) and Cb--752 (Nb--10W--2.5Zr) H'' sections continued. H'' extrusions (0.125 to 0.060 in. section thickness) showed reduced contamination and improved straightness, but surfaces and uniformity of section thickness were unsatisfactory. Extrusions were also drawn from section thickness of 0.188 in. at room temperature with reductions of 5 to 18% per pass. Total reductions up to 28% were made on short lengths without intermediate annealing. (auth)
