An experimental study of residual stress and direction-dependence of fatigue crack growth behaviour in as-built and stress-relieved selective-laser-melted Ti6Al4V (2019, unknown): “Gas pores and lack-of-fusion pores are typically formed in powder-bed additive manufacturing processes and have been reported previously [26,40].”
A numerical framework to predict the fatigue life of lattice structures built by additive manufacturing (2020, background): “This means that every strut had exactly the same fatigue properties, although experimental fatigue results on single struts are usually scattered [4, 29, 30, 10, 7].”
Influence of energy density on metallurgy and properties in metal additive manufacturing (2017, background): “However, most metal AM processes are multistep because post-processing measures such as heat treatment and hot isostatic pressing (HIP) are carried out to improve mechanical properties such as yield and tensile strengths, and to achieve favourable metallurgical mechanisms [14,15].”
Micromechanical behavior and thermal stability of a dual-phase α+α’ titanium alloy produced by additive manufacturing (2019, background): “SLM specimens includes a stress relief at 650°C for several hours [19], which induces a complete decomposition of the martensite [18,20,21].”
Residual stress and texture control in Ti-6Al-4V wire + arc additively manufactured intersections by stress relief and rolling (2018, background): “The temperature range of heat treatments for microstructural improvements [9], [10] or even hot-isostatic pressing [11], [12] typically exceed stress relieving temperatures and act therefore stress relieving by default.”
Additive manufacturing of Ti6Al4V alloy: A review (2019, unknown): “[45] utilized neutron scattering to measure residual stresses in EBM Ti6Al4V parts and did not measure a significant level of residual stresses.”
Review of Powder Bed Fusion Additive Manufacturing for Metals (2021, background): “[33] reported the fatigue strength of EBMbuilt Ti-6Al-4V alloy to be in the range of 200–250 MPa at 107, cycles which increased to 550–600 MPa at the same cycles after HIP due to a reduction in voids and porosity.”
