Combinatorial Investigation of Intermetallics Using Electron - Beam Deposition
Title of Dissertation: Combinatorial Investigation of Intermetallics Using Electron-beam Deposition Hiroyuki Oguchi, Doctor of Philosophy, 2008 Directed By: Professor Ichiro Takeuchi, Materials Science & Engineering We have systematically studied subtle changes in physical properties of intermetallics using the combinatorial strategy where a large number of samples with systematically changed p...
متن کاملEvaluation of Titanium Alloys Fabricated Using Rapid Prototyping Technologies—Electron Beam Melting and Laser Beam Melting
This study characterized properties of Ti-6Al-4V ELI (extra low interstitial, ASTM grade 23) specimens fabricated by a laser beam melting (LBM) and an electron beam melting (EBM) system for dental applications. Titanium alloy specimens were made into required size and shape for each standard test using fabrication methods. The LBM specimens were made by an LBM machine utilizing 20 µm of Ti-6Al-...
متن کاملValidation Experiments for LBM Simulations of Electron Beam Melting
This paper validates 3D simulation results of electron beam melting (EBM) processes comparing experimental and numerical data. The physical setup is presented which is discretized by a three dimensional (3D) thermal lattice Boltzmann method (LBM). An experimental process window is used for the validation depending on the line energy injected into the metal powder bed and the scan velocity of th...
متن کاملInvestigation of Tantalum Recycling by Electron Beam Melting
Investigations are carried out and obtained experimental and theoretical data for tantalum scrap recycling by electron beam melting (EBM) is presented in this paper. Different thermal treatment process conditions are realized and results are discussed. A chemical analysis is performed and refining mechanisms for electron beam (EB) refining of Ta are discussed. For the performed experiments the ...
متن کاملIntegration of a Thermal Imaging Feedback Control System in Electron Beam Melting
A thermal imaging system using an infrared (IR) camera was incorporated in the fabrication process of an Arcam A2 Electron Beam Melting system to provide layer-by-layer feedback and ensure quality and defect free products. Using the IR camera, build chamber surface temperature profiles were imaged and analyzed, providing information used to modify build settings for the next build layer. Indivi...
