Abstract

A novel, nickel-base, high temperature alloy body preferably containing about 20% chromium. 6 to 7% aluminum to provide gamma min phase, 1.5 to 2.5% molybdenum, 3 to 4.5% tungsten, additional strengthening elements and oxidic yttrium in finely dispersed form. The alloy body has an elongated crystal structure and is characterized by high strength along with excellent hot corrosion and oxidation resistance.
