Abstract
A mechanically alloyed composition of matter containing 30-40% chromium, 0-15% cobalt, 0-10% iron, 0.2-1.0% aluminum, 0.3-1.2% titanium, greater than 1-5% tantalum and/or niobium, 0.2-1% yttria, usual processing and trace impurities, and the balance nickel. The addition of tantalum improves the workability characteristics of the alloy. The alloy is particularly useful for molten glass spinners.
