Role of shielding gas in tailoring microstructure and anisotropy in wire arc additive manufactured Inconel 686.

This study examines the effect of shielding gas composition on the microstructure and mechanical properties of Inconel 686 components fabricated via wire arc additive manufacturing (WAAM). Thin-walled structures were produced using pure Argon (Ar), a 50% Helium-Argon mixture (Ar + 50% He), and pure Helium (He). Cooling rates were highest with pure He and lowest with pure Ar.

Effects of Infill Patterns on the Mechanical and Tribological Behaviour of 3D-Printed Polylactic Acid/Bamboo Biocomposites for Structural Applications.

Composite materials are gaining attention owing to their exemplary characteristics and, if the materials are eco-friendly, they attract much more. One such composite of poly lactic acid (PLA) combined with bamboo fiber in the ratio of 80:20 is selected for this study. The composites are manufactured using additive manufacturing, or the 3D-printing technique.

Cryo-laser synergy: Enhancing metallurgical and mechanical excellence in Inconel 59-AISI 904L joints.

This study evaluates the compatibility of dissimilar welding between Inconel 59 and Austenitic Stainless Steel (AISI 904L) using CO₂ Laser Beam Welding. The investigation includes macro and microstructure analysis, mechanical property evaluation, and the effects of cryogenic treatment. Weld geometry was assessed macroscopically, confirming process feasibility.

An Overview of the Additive Manufacturing of Bast Fiber-Reinforced Composites and Envisaging Advancements Using the Patent Landscape.

Natural fiber composites attract attention owing to their environmentally friendly attributes. Many techniques, including fiber treatment, coatings, and fiber orientations, are used to improve the strength of natural fiber-reinforced composites. Still, the strength needs to be improved as expected.

A Critical Review on Hygrothermal and Sound Absorption Behavior of Natural-Fiber-Reinforced Polymer Composites.

Increasing global environmental problems and awareness towards the utilization of eco-friendly resources enhanced the progress of research towards the development of next-generation biodegradable and environmentally friendly material. The development of natural-based composite material has led to various advantages such as a reduction in greenhouse gases and carbon footprints. In spite of the various advantages obtained from green materials, there are also a few disadvantages, such as poor interfacial compatibility between the polymer matrix and natural reinforcements and the high hydrophilicity of composites due to the reinforcement of hydrophilic natural fibers.
