An aluminized metallic scaffold for high temperature applications comprises a porous non-refractory alloy structure including a network of interconnected pores extending therethrough. The porous non-refractory alloy structure comprises a transition metal phase and an aluminide phase, and portions of the porous non-refractory alloy structure between interconnected pores have a thickness no greater than about 500 nm. A method of making an aluminized metallic scaffold for high-temperature applications comprises introducing aluminum into a surface of a porous metallic structure at an elevated temperature. The porous metallic structure comprises a transition metal and has a network of interconnected pores extending therethrough, where portions of the porous metallic structure between interconnected pores have a thickness no greater than about 500 nm. As the aluminum is introduced into the surface and diffusion occurs, an aluminide phase is formed, resulting in a porous non-refractory alloy structure comprising the aluminide phase and a transition metal phase.
