This patent describes a method for forming porous oxide dispersion strengthened molten carbonate fuel cell anodes having improved anode creep resistance. It comprises: forming a porous plaque of nickel-titanium alloy having between about 1--5 weight percent titanium; internally oxidizing the titanium without oxidizing the nickel by contacting the plaque with a gas mixture containing hydrogen and steam in a ratio of about 2 volumes steam to about 1 volume hydrogen for at least 10 hours at a temperature in the range from about 600{degrees} C. to about 900{degrees} C. to form the oxide dispersion strengthened anode.
