Researchers at Oak Ridge National Laboratory (ORNL) demonstrated that a new class of superalloys made of cobalt and nickel remains crack-free and defect-resistant in extreme heat, making them conducive for use in metal-based 3D-printing applications. In a study, researchers processed the cobalt and nickel class of superalloys and proved that they remained crack-free in electron-beam and laser-melting 3D-printing processes. According to ORNL, the superalloys have the material properties necessary for challenging environments because they successfully withstood the heat and also retained strength when stretched.
