TL;DR: In this article, it is shown that transitions in microstructure, texture, and properties in fabricated Inconel 718 functionally graded components can be obtained at relatively small or large length scales, depending upon the functional gradient desired in a particular application.

TL;DR: In this article, the microstructural design of Inconel 718 specimens produced by selective laser melting (SLM) was adjusted through process parameters manipulation and post-process heat treatment, and the effects of heat treatment on microstructure, process induced defects, deformation behaviour and failure mechanisms were studied.

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.

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: The findings show that fatigue life is significantly improved by applying developed herein novel method, which effortlessly can be used on other bone-mimicking metallic meta-biomaterials.
