Prediction and fabrication of textured Si3N4 ceramics via grain rotation model

Materials & Design
The grain preferential orientation has a significant influence on the mechanical properties of silicon nitride (Si3N4) ceramics. Based on the Jeffery’s theory, a grain rotation model under uniaxial compression is created to predict the texture evolution ...

Future Tense [PDF]

, 2020
Nature - Humans - Past - Future - Presence - Absence These familiar terms are the stepping stones of thought that went into my thesis work. While some may pair these words together as dichotomies, I concentrate on the balancing act that exists between

Texturing (Na_0.5Bi_0.5)TiO₃-KNbO₃-SrTiO₃ Electrostrictive Ceramics by Templated Grain Growth Using (Na_0.5Bi_0.5)TiO₃ Platelets

Inorganics
Electrostriction is an intriguing behaviour of dielectric materials, characterized by stable electrostrain with minimal hysteresis. (Na0.5Bi0.5)TiO3-based ceramics show promising electrostrictive behaviour, particularly the 0.90(Na0.5Bi0.5)TiO3-0.08KNbO3-

High-speed Fabrication of Micro-channels using Line-based Laser Induced Plasma Micromachining (L-LIPMM) [PDF]

, 2013
Micro-texturing of surfaces has various applications that often involve texturing over large (macro-scale) areas with high precision and resolution. This demands scalability and speed of texturing while retaining feature sizes on the order of a few ?m.

Frictional Behavior and Fluid Flow Simulation Analysis of Textured ZrO₂–Polyetheretherketone Artificial Knee Joints

Lubricants
ZrO2 ceramics, known for their high strength and wear resistance, are ideal for artificial joints. This study enhanced the friction performance of these joints by fabricating textured structures (50 μm width and 20–25 μm depth) on the ceramic surface ...

Texture in Aluminum Titanate Ceramic Materials

Texture, Stress, and Microstructure, 1995
Dry pressing and filtration of a mixture of platelike corundum and rutile powders shows a slight to sharp texture of the corundum particles. The reaction sintering forming aluminum titanate destroys the texture of the green compact. When starting with a rutile texture in the green compact there exists a texture of tielite in the reaction product ...
