Microstructure and mechanical properties of additive manufactured copper alloy
TL;DR: In this article, the microstructure of the SLM material consists of grains elongated along build direction with the size in the range from 30 to 250 µm, and the mechanical test showed that the material has 195-211 MPa ultimate tensile strength (UTS) and 11-16% elongation at break at 20 µm.

The Effect of Layer Thickness at Selective Laser Melting
TL;DR: In this article, the correlation between powder layer thickness and relative density, microstructure and mechanical properties of nickel-based superalloy produced by selective laser melting is presented, and it is shown that the size of columnar dendritic cells depends on the layer thickness used during SLM.

TL;DR: In this paper, the effect of the process parameters of selective laser melting (SLM) on the structure and properties of Inconel 718 specimens is discussed, and the results of uniaxial tension experiments on homogeneous specimens, as well as on structurally graded specimens with equiaxed fine grains and elongated coarse grains, are presented.
Effect of Heat Treatment on the Structure and Phase Composition of a High-Temperature Nickel Alloy Obtained by Laser Cladding
TL;DR: In this paper, the effect of the heat treatment modes on the structure and phase composition of the alloy is analyzed and the gas-powder flow is optimized as a function of the flow rate of the protective and transporting gas.
