PROPERTIES OF ARC-MELTED CHROMIUM-BASE ALLOYS

Description: screened for hot workability, oxidation resistance, and hot strength using small arc-melted ingots. The alloying elements investigated included Fe, Mn, Mo, Nb, Re, Ru, Ta, Ti, W, V, Zr, and Y in amounts up to 20 wt%. Of the fabricable alloys tested, the best combinations of oxidation resistance and strength, in the range of 2000 to 2300 deg F, were found in binary alloys containing 5 wt % molybdenum, 10 wt% tungsten, and 2 wt% niobium. While yttrium additions do not contribute to the hot strength of chromium, the effectiveness of yttrium in improving the oxidation resistance of chromium is outstanding. About 1 wt% yttrium appears optimum for this purpose. Experiments with the preparation of large chromium-base alloy ingots showed that cold-mold arc melting was not suitable for preparing ingots containing over about 1 wt% of alloy addition. However, the feasibility of preparing sound, higher alloycontent ingots by induction melting and casting was demonstrated. (auth)

Theoretical pressure distribution and wave drags for conical boattails

Description: "Afterbody pressure distributions and wave drag were calculated using a second-order theory for a variety of conical boattails at zero angle of attack. Results are presented for Mach numbers from 1.5 to 4.5, area ratios from 0.200 to 0.800, and boattail angle from 3 degrees to 11 degrees. The results indicate that for a given boattail angle, the wave drag decreases with increasing Mach number and area ratio" (p. 1).
