An original approach based on 2D fracture surface and 3D X-ray tomography analysis is proposed in this paper. Its application in selective laser melting of Ti-6Al-4V provides substantive clarifications regarding both mechanisms of porosity formation and their influence on mechanical properties. Unambiguously, a one-to-one relationship between the scanning strategy pattern and the 3D spatial distribution...
Short-range ordered aluminosilicates particles were synthesized on the basis of a sol–gel process with initial solutions containing decimolar concentrations of AlCl 3 salts and Si alkoxide (tetraethyl ortho silicate) with varying Al/Si molar and hydrolysis OH/Al ratios. Transmission electron microscopy micrographs revealed more or less condensed aggregates displaying homogeneous elemental...
