| Abstract Scope |
Mo-Si-B alloys are attractive alternatives to Ni-based superalloys to improve energy efficiency of gas turbine systems. Using advanced electron microscopy techniques and density-functional theory (DFT), we identified the phase, crystal structure and chemical distribution of the Mo-Si-B-Ti alloys manufactured with directed energy deposition (DED). Transmission electron microscopy was used to characterization the crystal structure, atom arrangement and alloying element distribution. DFT calculations were performed to understand the results from TEM. |
