title = "Effect of process control and powder quality on inconel 718 produced using electron beam melting",
abstract = "Powder bed additive manufacturing technologies have the potential to fabricate complex metal components with increased performance at lower costs than conventional processes. The Arcam Electron Beam Melting (EBM) process distributes metal powder in thin layers (50-200μm) which are melted by a focused electron beam at specific locations specified by a computer file. Work is presented that demonstrates the ability to fabricate Inconel 718 components from powder and discusses challenges with reference to process control and final properties. Processing defects may be avoided by changing the power/velocity relationship and powder bed temperature. Powder quality also plays an important role in additive manufacturing metallurgy, and the effect on EBM parts is explored. The importance of the hold time and hold temperature of the part during fabrication greatly affect tensile properties in the results presented. The relationship between processing parameters, powder quality, and mechanical properties is discussed.",
