PURPOSE:To obtain a superheat resistant single crystalline Ni alloy having superior creep rupture strength and a stable structure by adding specified amounts of Cr, Al, W, Ta and Mo to Ni and regulating the total amount of W, Ta and Mo added to a specified value. CONSTITUTION:The composition of a superheat resistant single crystalline Ni alloy is composed of, by weight, 4-10% Cr, 4-6.5% Al, 4-10% W, 4-9% Ta, 1.5-6% Mo and the balance Ni with inevitable impurities and the total amount of W, Ta and Mo added is regulated so as to satisfy the formula.
