OXIDIZING RESISTANT AND CORROSION RESISTANT ALLOY FOR MEMBER USED IN INTERMEDIATE TEMPERATURE RANGE, CONSISTING ESSENTIALLY OF ADDED IRON ALUMINIDE

摘要

PURPOSE: To produce an alloy having oxidation resistance, corrosion resistance in the intermediate temp. range (300-700°C) and heat resistance and sufficient ductility at room temp. and a low temp. and suitable for directional solidification. ;CONSTITUTION: This alloy contains 24-28 at% Al, 0.1-2 at% Nb, 0.1-10 at% Cr, 0.1-1 at% B, 0.1-2 at% Si and the balance Fe. The alloy has 500-650 MPa yield point at 550°C.;COPYRIGHT: (C)1992,JPO
