Cone dimensions are base; 8-inch inside diameter; top, 4-inch inside diameter. This alloy is highly reactive - similar to tantalum. It must be hot rolled at 1800-2000F and protected from oxidation. To weld a one-half inch weld gap would require a fair amount of filler wire which would have to...
Need to make a frustrum of a cone using niobium-30w/oTi-20w/o W alloy. 0.5-inch wall thickness. Two possible fabrication techniques have been posed. Use powder met and HIP to near net shape. Roll plate and form and seam weld. The later isn't attractive for several reasons. Does anyone know...
