A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Statistical Treatment of Welding Deformation(Report 1). Statistical Property of Welding Deformation in Fillet Welding Tee Joint Flange.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1999
At present, the parameters to control the welding deformation of the basic welding joints have been made almost clear and, to some extent, they can be estimated from the welding conditions. However, the welding deformation is expected to depend on welding operators because it is affected by the welding conditions such as welding heat input, leg length,

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
