Microstructure, texture, and mechanical properties of electron-beam melted Ti–6Al–4V

An Overview of Densification, Microstructure and Mechanical Property of Additively Manufactured Ti-6Al-4V — Comparison among Selective Laser Melting, Electron Beam Melting, Laser Metal Deposition and Selective Laser Sintering, and with Conventional Powder

“…Arcam provides a variety of EBM machines for processing Ti and Ti alloys, including Arcam A1, A2, S12 and S400, and it dominates the market for the time being [47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. Figure 3 provides a schematic graph to show the working principle of the EBM [66]; key machine parameters and working conditions are summarised into …”

Welding of Thin Light Alloys Sheets by CO2 Laser Beam: Magnesium Alloys

“…The most likely explanation for the variation of texture between the surface and the depth of the fusion zone is that the differences of the thermophysical and thermomechanical properties of the investigated location affect the process of solidification and plastic deformation, leading to different final out-comes. In our study, the nature of this texture has been explained by the thermodynamic conditions of minimisation of surface energies a) On the surface b) to 50 μm c) to 150 μm d) to 200 μm (Kalinyuk et al, 2003;Matysina, 1999) which results in the presence of columnar grain growth at the surface of the welded zone (Kurtz et al, 2001). Between the surface and the 200 µm depth (Figure 7b, 7c, 7d) the texture decreases to disappear completely from 200 µm.…”

Study of Mechanical Properties of AZ91 Magnesium Alloy Welded by Laser Process Taking into Account the Anisotropy Microhardness and Residual Stresses by X-Ray Diffraction

“…For the microstructural and anisotropic properties aspects we have based our work on the previously published public work [14] and references [3,20,21,22,23] which give a detailed description of microstructure and crystallographic texture modifications induced by laser welding.…”
