Process and Properties of Nibased 718 Superalloy Formed  by Selective Laser Melting by YU Yandong, LI Jian, HU Haiting

“…In order to study the effect of laser processing parameters of selective laser melting technology (SLM) on the relative density, Vickers hardness and microstructure of Inconel 718, the FORWEDO LM120 laser melting equipment was used to study four laser processing parameters, namely the scanning speed, laser power, laser energy density and scanning strategy to improve the performance of the workpiece The results show that the scanning speed and laser power are the main factors affecting the formability, and the optimized process range: laser power (285~345W), scanning speed (950~1150mm/s) can gain the workpiece of 9894% relative density with fewer defects of voids and cracks The tensile strength and the yield strength of the workpiece are close to those of the traditional forging and annealing processes The heat dissipation characteristic leads to the difference of the histomorphology of the specimen, and in the stratification direction, columnar crystals directionally solidify The Vickers hardness of the sample increases with the refinement and densification of the structure…”

Lessons learnt from the 2021 Pacific Northwest heat dome: a qualitative study of western Washington’s healthcare community response by Nathaniel Matthews-Trigg, Jeremy Hess, Amruta Nori-Sarma, Kelly Hill, Matias Korfmacher, Cat Hartwell, Gregory Wellenius, Nicole Errett

“…Establishing centralised coordination ahead of heat events, making improvements to the cooling capabilities of the built environment, developing plans and policies for EHEs that have co-benefits for other events, adopting evidence-informed response strategies, institutionalising the knowledge and relationships developed through prior events and improving evaluative processes (such as developing real-time monitoring capacity) will enable more effective response to future EHEs.Conclusions Western Washington’s health sector implemented EHE response activities that enabled essential service continuity, despite limited resources, unfamiliarity with EHEs and other systemic challenges. …”

Thermal degradation and spectroscopy characterizations of TPS/PBAT blends irradiated by Cobalt-60 source by Dione Pereira de Castro, Leonardo Gondim de Andrade e Silva

“…According to the results obtained in the FTIR tests, the blends did not undergo chemical changes during the irradiation process and, thus, maintained their properties. In the DSC tests, it was observed that the blends F2 (castor oil) and F3 (castor oil and TWEEN® 80) showed higher values of heat flow for degradation than the samples F0 (glycerol) and F1 (glycerol and TWEEN® 80), probably due to the chemical interaction of castor oil and its constituents. …”
