A powder metallurgy method of making a chromium base alloy includes blending a first powder comprising a chromium powder and a second powder comprising at least one of titanium, titanium hydride, zirconium or zirconium hydride, annealing the first powder and the second powder in a reducing atmosphere after the step of mixing, compacting a blend of the first and the second powders, and sintering the compacted blend to form a chromium base alloy. The chromium alloy may be used as an interconnect for a solid oxide fuel cell, and includes least one of iron or nickel greater than zero and equal to or less than 7 weight percent, yttria greater than zero and equal to or less than 2 weight percent, at least one of titanium or zirconium greater than zero and equal to or less than 1 weight percent and at least 90 weight percent chromium.
