Forming Defects Analysis and Process Setting of Hot Rolling Technology of Hypoid Gear

open access: yesJixie chuandong, 2020
A theoretical analysis of the forming defect in the hot rolling forming process of a hypoid gear wheel is performed. It is found that defects occur during the hot rolling process, such as “lugs”.

Analytical inverse solution for coupled thermoelastic problem for the evaluation of contact stress during steel strip rolling [PDF]

open access: yes, 2013
International audienceKnowledge of the contact stress between roll and strip is a critical factor in modern, high-speed rolling mills. Previously two inverse analytical methods have been developed to determine the elastic contact stress on the one hand ...

Thermo‐Fluorescent Bactericidal Quantum Dots Based Smart Multifunctional Textiles via Molecular Surface Engineering and 3D‐Printed Interlocked Architectures

open access: yesAdvanced Healthcare Materials, EarlyView.
A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.

Simulating thermo-mechanical and microstructural phenomena in a laboratory-scale hot rolling mill

open access: yesMaterials & Design
Developing and validating metallurgical models for microstructural evolution during hot rolling was the aim of this work. In earlier studies recrystallization and grain growth have been simulated and combined with the academic version of the Virtual ...

Rolling-element fatigue life of silicon nitride balls [PDF]

open access: yes
The five-ball fatigue tester was used to evaluate silicon nitride as a rolling-element bearing material. Results indicate that hot-pressed silicon nitride running against steel may be expected to yield fatigue lives comparable to or greater than those of

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Effect of Finishing Rolling Temperature on Actual Grain Size of Hot Rolled Medium Carbon Boron- Containing Steel 40B

open access: yesTeshugang, 2020
The effect of finishing rolling temperature (880 〜935℃) on the actual grain size of hot rolled medium carbon boron steel 40B has been studied. With start rolling at 990 〜1010℃ , the different finishing rolling temperatures are achieved by controlling the
