Studies of friction and wear characteristics of various wires for wire-brush skids [PDF]
The friction and wear characteristics of 22 types and sizes of wires for potential use in wire-brush skids were studied. These characteristics were determined by placing brushes made from candidate wires on a belt sander whose moving belt simulated ...

steel research international, EarlyView.Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

steel research international, EarlyView.This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Journal of Vinyl and Additive Technology, EarlyView.Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

Non‐destructive orientation tracking of individual β‐Sn grains in die‐attach solder joints
Journal of Synchrotron Radiation, EarlyView.This study introduces inclined scanning three‐dimensional X‐ray diffraction microscopy (i‐S3DXRD) that enables three‐dimensional orientation mapping of planar polycrystalline materials, revealing the thermal fatigue mechanism of Pb‐free solder joints.Understanding the failure mechanisms of Pb‐free solder joints during thermal cycling is a critical ...

Contact Dermatitis, EarlyView.From January 2024 to May 2025, 207 patients (68.6% females) affected by CHE were enrolled to be clinically and etiologically investigated using a case report form specifically developed. The accurate workup led to clinical and etiological classification of CHE in about 80% of patients, allowing tailored treatment strategies. ABSTRACT Background Chronic

Contact Dermatitis, EarlyView.This Finnish registry study shows that concomitant occupational asthma and rhinitis are common in patients with occupational contact urticaria or protein contact dermatitis, often sharing the same exposure. When evaluating occupational immediate allergy, both skin and airway symptoms should be considered.
