Electron Beam Melted Parameter Development Of Pure Tungsten & Post-Processing Hip And Heat Treatment Of Gamma Titanium Aluminide, Kurtis Isami Watanabe

Open Access Theses & Dissertations

Pure tungsten is a refractory metal and has been gaining interest for the use in nuclear fusion reactors as a plasma facing material. Titanium Aluminide (TiAl) has been growing in popularity as a possibly to phase out Nickel based superalloys due to its high specific strength at elevated temperatures. These two materials suffer from poor machinability due to being brittle at room temperature. Additive manufacturing (AM) is a recently developed manufacturing method that is fundamentally different than formative or subtractive. AM is a layer-by-layer process that has the potential to manufacture metals to a near net shape. Since the AM …
