摘要:
The disclosure provides for a layered metal with resistance to hydrogen induced cracking and method of production thereof, comprising a core metal alloy and a skin metal alloy. The core metal alloy comprises twinned boundaries. The core metal alloy has undergone plastic deformation and a heat treatment. The core metal alloy comprises nickel and cobalt. The skin metal alloy is disposed on the core metal alloy, wherein the skin metal alloy comprises an entropy greater than the core metal alloy. The core metal alloy comprises a greater density of twinned boundaries than the skin metal alloy. The skin metal alloy comprises a stacking fault energy of at least about 50 mJ/m2, and the skin metal alloy comprises iron, aluminum, and boron.
