A method of making a metallic material includes mechanically alloying base metal with corrosion inhibitor to thereby form an alloy having the base metal and the corrosion inhibitor. A method of preventing corrosion includes providing the alloy to a process environment, allowing the process environment to corrode or crack the alloy to thereby expose the corrosion inhibitor of the alloy to the process environment, allowing a first ionic component of the corrosion inhibitor to be transformed to a second ionic component, and allowing the second ionic component to be repassivated with the alloy to thereby prevent further corrosion or cracking of the alloy.
