Abstract : Phase I goal is the extrusion of D-43 (Cb-10w1Zr-0.1C) and Cb-752 (Cb-10W-2.5Zr) 'H' sections of specified size, with section thickness of 0.060 in, and lengths of at least 20 feet. Two 8-in. diameter ingots were melted of each alloy, converted to billets, and extruded to 3.7 in. diameter stock. Nine 3.4-in.-diameter billets were extruded to 'H' sections with thicknesses of 0.187 and 0.125 in. (extrusion ratios of 12.4:1 and 18.2:1), from 3400 F. Phase II goal is the drawing of extruded 'H' sections of the above alloys to specified size, with section thicknesses of 0.040 in., and lengths of at least 20 feet. (Author)
