Abstract
A carbide reinforced iron based superalloy material is described. The material consists of an austenitic matrix containing about 30 volume percent aligned M.sub.7 C.sub.3 phase fibers. Fiber alignment is produced by directional solidification. A nominal alloy composition (by weight) is 20% Cr, 10% Mn, 5% Al, 3.2% C. balance iron. The alloys are characterized by the absence of strategic elements, are east to process and have superior mechanical properties to the known prior art, low nickel, iron base superalloys.
