“…Nickel-based superalloys hold a significant position in LPBF due to their excellent strength [40][41][42], oxidation resistance, and corrosion resistance, as well as their ability to maintain mechanical properties at high temperatures. These alloys are widely used in high-temperature and high-stress environments, such as turbine blades, jet engine components, and rocket engines in aerospace, gas turbines and nuclear reactor components in power generation, high-pressure and corrosive environment parts in the oil and gas industry, and turbocharger impellers and high-performance engine components in automobiles.…”
