Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

open access: yesPolymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...

Effect of Antioxidants and Compatibilizers on Gel Formation and Film Quality of Polyethylene Films With Recycled Content

open access: yesPackaging Technology and Science, EarlyView.
This paper and evaluates the quality variations that arise from the difference in PCR PE batches of the commercially produced films with PCR PE content then studies the effect of antioxidants and compatibilizers on the gel presence and seal characteristics of packaging films produced from 100% PCR PE.

Bio‐Based Transparent Self‐Healable Polyimides Enabled by Isosorbide‐Derived Dianhydride Design and Aliphatic Chain‐Mobility Regulation

open access: yesSmall, EarlyView.
Transparency, toughness, and self‐healing rarely coexist within a single polyimide. This bio‐based aliphatic–aromatic film resolves that conflict. An isosorbide‐derived dianhydride and a fatty diamine cooperatively suppress charge‐transfer complexes, yielding a colorless film that heals rapidly under mild heat, retains its toughness, and restores ...

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

open access: yessteel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

open access: yessteel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...
