Enhancing Strength and Corrosion Resistance of Steel-Reinforced Concrete: Performance Evaluation of ICRETE Mineral Additive in Sustainable Concrete Mixes with PFA and GGBS by Kowshika V.R, Vijaya Bhaskaran, Ramkumar Natarajan, Iman Faridmehr

“…The results revealed that ICRETE-enhanced mixes achieved compressive strengths of 56.93 MPa at a water–cement ratio of 0.35 and 50.61 MPa at 0.38, surpassing the control mix’s 50.9 MPa at 0.33. Microstructural analysis via X-ray diffraction (XRD) and scanning electron microscopy (SEM) showed that ICRETE improved hydration, reduced porosity, and refined the microstructure, contributing to more excellent durability. …”

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…”

The effect of Zn content on the age-hardening response and precipitation behavior for Al–8Si-0.6Mg-0.1Cu alloys by Lili Hu, Chenggang Wang, Feng Li, Jingqi Zhang, Maohui An, Jinguo Wang, Ruifang Yan

“…However, for the sample of 0Zn and 0.9Zn, the precipitates consist of β'' phase and trace Q′ phase, the Mg–Zn precipitation phase is not found in the microstructure. Finally, a precipitation schematic is proposed based on the precipitation behaviour of the three alloys, which reveal the evolution of the microstructure of the Al–8Si-0.6Mg-0.1Cu-XZn (X=0, 0.9, 3.6) alloy.…”
