TL;DR: In this article, the impact of different nozzle temperatures and printing speeds on 3D-printed polypropylene (PP) samples was examined, showing that high nozzle temperature, low printing speed reveals a homogeneous morphology, weak flow-induced orientations, isotropic thermal conductivities and a strong inter-layer diffusion.

TL;DR: In this article , the quench rate sensitivity of an Al-Mg-Zn-Cu alloy with low Zn/Mg ratio is investigated and compared to a commercial reference Al-Zmg-zn-cu alloy (AA7075) showing a high Zm/mg ratio.

TL;DR: In this paper, the mechanisms that govern the microstructure formation of an Al-Mg-Zn-Cu crossover alloy during wire-arc additive manufacturing are investigated. But the authors focus on the formation of Mg-, Zn- and Cu-rich phases on different length scales spanning from ~10 µm (microsegregations), down to a few nm (bulk) following the intrinsic heat treatment.

TL;DR: In this paper, the authors investigated the underlying strengthening mechanisms of near-α alloys by means of spark plasma sintering, along with sufficient room temperature ductility and detailed microstructural characterization.
