Abstract: Reduction of the buy-to fly ratio through the utilisation of lean manufacturing processes for the next generation of components is an increasing area of interest in the aerospace industry. Powder bed Electron Beam Melting (EBM) is now rapidly being acknowledged as an innovative form of Additive Layer Manufacturing (ALM) with the potential to produce near-net shaped final components. Before its potential can be fully realised, microstructural irregularities such as porosity must be addressed by undertaking a comprehensive evaluation of the process variables that relate to microstructure and mechanical properties. The anisotropic nature of EBM Ti alloys is understood to be a result of intra-build variations for which conventional experimental data has been collected. However post-test analysis has revealed a series of anomalies within the resultant microstructure, some of which have which have received limited coverage in contemporary literature. As such, Vickers hardness assessment has been combined with X-Ray computer tomography and microscopy to discuss the findings
