High temperature alloy powder is usually an alloy powder with special heat resistance properties, composed of two or more metal elements, and must contain a certain proportion of high-temperature heat-resistant elements such as nickel (Ni), iron (Fe), cobalt (Co), tungsten (W), chromium (Cr), etc. These alloy powders have good high-temperature oxidation resistance, high-temperature strength, high-temperature fracture toughness, and heat fatigue resistance, and can operate stably for a long time in high-temperature environments. Therefore, high-temperature alloy powders are widely used in the manufacturing of high-temperature components in aviation, aerospace, energy, chemical and other fields, such as turbine engine blades, gas turbine components, high-temperature synthesis devices, and chemical process equipment. At present, high-temperature alloy powders have become one of the research hotspots in the field of metal 3D printing or additive manufacturing. The components manufactured through technologies such as 3D printing can be more precise and meet the requirements of complex structures.
