Manufacturing of Udimet using Powder Bed Fusion and Evaluation of its Mechanical Properties
Udimet is a superalloy which possesses exceptional strength, corrosion resistance, and high-temperature stability in which they are primarily used in applications where materials must withstand extreme environments, such as in the aerospace, automotive, and energy industries. Casting and forging are the conventional metallurgical processing techniques that can be used to manufacture superalloys. Here, udimet alloy is being produced using one among the most versatile additive manufacturing processes, laser powder bed fusion. The manufacturing method referred to as Laser Powder Bed Fusion (LPBF) involves building three-dimensional components out of successive layers of material in which it enables the production of intricate geometries and patterns that are challenging or impossible to produce using conventional manufacturing techniques. By utilising laser energy, this particular type of additive manufacturing technique selectively melts and fuses metal powder into solid objects. This paper's goal is to give a general overview of the udimet alloy, which is made using a laser powder bed fusion process, as well as to summarise its key process parameters, mechanical properties, and metallurgical flaws and potential control strategies, all of which directly affect its mechanical properties.
