- Abstract
A wire and arc additive manufacturing process for superalloy Hastelloy X was developed. The effects of parameters in the TIG based process were investigated using the Taguchi method and an analysis of variance. Multi-layer deposition strategies were tested and no significant difference was found between printing layers in the same direction or in alternating directions. In preliminary trials, three distinct zones were identified and characterized by the size and distribution of molybdenum carbides. By refining the process, resulting multi-layer samples exhibited less variation in the size and shape of molybdenum carbides. The isothermal oxidation behavior of AM Hastelloy X was compared to the wrought alloy through testing in air at 1080°C. The parabolic oxidation rate constant of the AM samples was determined to be 4.54×10-8 g2/cm4/h. Results suggest that the AM samples may have an advantage in oxidation resistance however weight gains were quite similar suggesting an equivalent oxidation behavior.
