Al3Ni and Al3Ti alloys were prepared by arc melting and exposed to chemical leaching in 5M NaOH at room temperature. In case of Al3Ni alloy, Al reached phases react with the leaching solution to produce nanoporous nickel with a pore diameter in the range of ~10–20 nm. Only pure Al phase of Al3Ti alloy chemically reacts with the production of a dense wrinkled surface with a wrinkle size of ~50–100 nm.
