Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Synthesis and Characterization of Nano-Sized Nickel Aluminate Spinel Crystals

open access: yesInternational Journal of Electrochemical Science, 2013
X-ray diffraction (XRD) of nickel aluminate showed its structural properties such as crystallite size, lattice constant, unit cell volume and X-ray density. The nano-sized nickel aluminat (NiAl2O4) crystals were prepared in this study.

Micro-Raman, FTIR, SEM-EDX and structural analysis of the Çanakkale meteorite

open access: yesSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2012
This study demonstrates for the first time, the spectroscopic characterization of Çanakkale Meteorite that fell at Çanakkale, Republic of Turkey (40°8'44″N; 26°24'23″E). The olivine group [(Mg, Fe)(2)SiO(4)], enstatite [Mg(2)Si(2)O(6)] (one of the orthopyroxene minerals) and plagioclase were identified by the micro-Raman and FTIR spectroscopies and EDX-

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

open access: yesAdvanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Effects of Mg on Microstructure and Solidification of a Hypereutectic Zn–8 wt.%Al Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
An appreciable set of results involving thermal data, microstructure, chemical composition, and microstructural growth laws is reported for ZnAlMg alloys. Such results demonstrate that ZnAlMg alloys have high potential for applications in automotive self‐lubricating components, batteries, and electrical systems.

Gyroid Structured Globugraphite Carbon Foam With Hierarchical and Tailored Pore Size

open access: yesAdvanced Engineering Materials, EarlyView.
Secondary sacrificial templates were designed and printed to create a defined network within a porous carbon. Lattices thermally degrades during the sintering process. Lattices are imprinted into the ceramic template and transferred to the morphology of Globugraphite.

SEM-EDX STUDIES OF CHITOSAN DERIVATIVES-METAL ADDUCTS

open access: yesJournal of the Chilean Chemical Society, 2003
Chitosan was obtained from shrimps shells (pleuroncodes monodon) using chemical methods. A series of chitosan (QS)charged with solution of copper, cobalt, nickel and mercury ions were prepared at room temperature using the batch method. N-3,5-diethylamino benzoyl chitosan (QDAB); N,O-dimercapto succinate chitosan (QNOT) and 4-aminobenzoate chitosan ...
