Preparation of lanthanum zirconate nano-powders by Molten Salts method

open access: yes, 2010
Pyrochlore La(2)Zr(2)O(7) nano-powders with cubic structure have been firstly prepared by Molten Salts method. These nano-powders were prepared at a relatively low temperature using La(NO(3))(3)center dot 6H(2)O and ZrOCl(2)center dot 8H(2)O as raw ...

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination

open access: yes, 1998
Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders ...

Synthesis of silica powders by pressured carbonation

open access: yes, 2009
A method was proposed for the preparation of silica powders using inexpensive material of sodium silicate (Na(2)SiO(3)) and carbon dioxide (CO(2)) by pressured carbonation, in which carbon dioxide acted as a precipitating reagent. Microstructure and size

Electrodeposition in Structural Lattices of Variable Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

open access: yesAdvanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

Microstructural Evolution and In Situ Formation of TiB and TiC in Ti─5Al─2.5Sn Alloy Processed by Powder Metallurgy

open access: yesAdvanced Engineering Materials, EarlyView.
Accelerated in situ formation of TiB and TiC in Ti–5Al–2.5Sn–B4C is driven by transient liquid phase formation, which enhances particle reactions and microstructural evolution. This process increases hardness and establishes a coupled relationship between sintering temperature and reinforcement content, strongly influencing porosity in the resulting ...
