Clean recycling of spent nickel-based single-crystal superalloy by molten magnesium
Nickel-based single-crystal superalloys are designed for extreme conditions due to their superior corrosion and creep resistance properties.However, these pose challenges in the subsequent recycling after reaching their end-of-life.Molten magnesium (Mg) can rapidly corrode the stable spent nickel-based superalloys and selectively dissolve nickel (N
