Inconel 718 - Mainstream 3D Printing Material for Additive Manufacturing

After World War II, the word "superalloy" came into being to describe a kind of high-performance alloys, which was specifically developed to extend the service life of aircraft parts exposed to extreme high temperature. Superalloy with nickel, iron, cobalt as the base, through the addition of alloy elements to achieve a variety of metal characteristics of super fusion, can work above 600℃ high temperature and a certain stress for long-term, become the mainstream material of aerospace, petrochemical, racing and other industries. Some studies show that the Inconel 718 accounts for more than one third of the nickel-based superalloy used in aerospace engines.

According to the Carnot cycle, running an engine at higher temperatures can improve energy efficiency, which in turn makes the engine more energy-efficient. The inconel 718 3d printinghas become a cornerstone of aerospace applications. It also has important applications in nuclear reactors (heat exchanger pipes), submarines (propeller blades, quick cut-off devices, auxiliary propulsion motors), chemicals (vessels, pumps, valves, pipes), power generation (industrial gas turbines), and the oil and gas industry (downhole pipes, wellhead hardware, torch arms).

Traditional manufacturing methods, such as machining, forging or welding, usually require heat treatment before the process begins, thus affecting the temperature corrosion and creep resistance of components. However, the mechanical properties of 3d printed In718 have not been sacrificed, and can even exceed those of cast or forged parts. In addition, Inconel 718 is difficult to machine because of its high cutting temperature and severe work hardening. For the complex geometries commonly required in aerospace applications, the Inconel 718 parts are often difficult and costly to manufacture.
