摘要
PROBLEM TO BE SOLVED: To provide a Ni-Fe-based alloy preferably usable as a member of a high temperature device such as a gas turbine.;SOLUTION: A Ni-Fe-based alloy has a composition containing, by mass%, Fe:30 to 40%, Cr:14 to 16%, Ti:1.2 to 1.7%, Al:1.1 to 1.5%, Nb:1.9 to 2.7% and by mass.ppm, P:over 150 ppm to 500 ppm and one or two kinds of Mg:0.01% or less and Zr:0.1% or less if desired and the balance Ni with inevitable impurities, suitably is grain boundary reinforced so that deposition containing P is deposited at grain boundary and a grain boundary coating percentage defined by a percentage of length of the grain boundary coated by the deposition containing P to length of the grain boundary is 20% or more.;COPYRIGHT: (C)2015,JPO&INPIT
