Rolling contact fatigue of silicon nitride. [PDF]
Silicon Nitride has traditionally been used as rolling contact bearing material owing to its superior performance compared to bearing steels. Its successful application as a bearing element has led to the development of Silicon Nitride in other rolling ...

Comparison of 4-ball and 5-ball rolling contact fatigue tests on lubricated Si3N4/steel contact [PDF]
Accelerated four-ball and five-ball rolling tests were performed on HIPed Si3N4 ball samples (rough lapped with surface roughness value Ra0.08 μm and Rq0.118 μm) in fully lubricated condition.

Some problems in hot rolling of al-alloys solved by the finite element method [PDF]
This thesis is focused on employing the finite element method (FEM) to simulate hot flat rolling process. The relevant work involves selecting a suitable constitutive equation, predicting the rolling load and roll torque, computing temperature changes ...

Contact Pressure Measurement System in Cross Wedge Rolling [PDF]
In the cross wedge rolling process (CWR), plastic deformation is geared by a driving torque transmitted by friction on die surface. Friction plays a role which has to be further identified in this metal forming process. The local contact pressure between

A Quick Policy to Filter Reactions Based on Feasibility in AI-Guided Retrosynthetic Planning [PDF]
A neural network-guided Monte Carlo tree search (MCTS) has been shown to be a promising algorithmfor computer-aided synthesis prediction. Here we train and investigate a filter policy that removesunfeasible reactions from the search. We investigate three

Residual stress field of HIPed silicon nitride rolling elements [PDF]
The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3 to 10.87 kgf/ball and four kinds of commercially finished 1/2 in (12.7 mm ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.

Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
