Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Properties of E-51/DDS Epoxy Resin Toughened by Alkaline EP_b-POSS

Cailiao gongcheng, 2016
The bisphenol A epoxy resin (E-51)/4,4'-diaminodiphenyl sulfone (DDS) was modified by the epoxy silsesquioxane (EPb-POSS), which was synthesized by hydrolytic condensation of (γ-glycidoxypropyl)trimethoxysilane under basic condition, to prepare EPb-POSS ...

High-temperature toughening in ternary medium-entropy (Ta1/3Ti1/3Zr1/3)C carbide consolidated using spark-plasma sintering

Journal of Asian Ceramic Societies, 2020
We report for the first time the effect of temperature on the mechanical properties of (Ta1/3Ti1/3Zr1/3)C carbide. Flexural strength and fracture toughness were investigated using the three-point bending technique in argon.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

The influence of the oxygen equivalent in a gas-mixture on the structure and toughness of microalloyed steel weldments [PDF]

Journal of the Serbian Chemical Society, 2006
Testing were carried out on two steels. The first was microalloyed with Nb and second with Ti, Nb and V. The impact toughness of weld metals of these steels was evaluated using an instrumented Charpy pendulum.
