Gamma Irradiation Effects on Structural and Optical Properties of PVA/Al₂O₃/TiC Polymer Nanocomposites for Optoelectronic Applications
Abstract: PVA/TiC/Al2O3 nanocomposite (PTA) films were successfully prepared via the solution casting method. The impact of high-dose gamma (γ) irradiation (30 kGy) on the structural and optical properties of PVA/TiC/Al2O3 nanocomposites was systematically explored using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and UV–Visible spectroscopy. XRD analysis confirmed the semi-crystalline nature of the nanocomposites, which was found to decrease upon incorporation of Al₂O₃ nanoparticles and exposure to …

Comparative Investigation on Mechanical Properties of AMCs Fabricated through Liquid and Solid-State Fabrication Process
Abstract: This current research work is primarily focused on comparative experimental study on effect of two distinct fabrication process routes i.e. liquid state and solid state process and their corresponding parameters on microstructure and micro-hardness properties of Aluminium matrix composites (AMCs). In this work, AMCs were fabricated by reinforcing Al2O3 powder materials of 5, 10 and 15 wt.% into pure Aluminum (Al) matrix phase through two distinct processes; liquid state (stir …

Influence of Dielectric and Active layer Thickness on MgZnO Thin Film Transistor Electrical Characteristics
Abstract: From last decades, Thin Film Transistors Technology uses low-k dielectric material as an insulator. Insulator thickness plays an important role in device dimension. The insulating layer also known as the gate oxide separates the gate electrode from the channel region of the transistor. If the insulating layer is too thin, there is a greater chance that electrons can tunnel through the oxide layer, leading to leakage current. To mitigate this …

Influence of Different Fluxes on the Angular Distortion of A-TIG Welded 316L Steel Plates
Abstract: The conventional Tungsten Inert Gas (TIG) welding process is an autogenous welding process primarily used to weld thin metal sheets in the food processing and chemical industry. The process can weld almost all engineering materials but suffers from the limitation of slow speed and inability to weld thick sections. With the development of A-TIG welding, some of the drawbacks of traditional TIG welding have been addressed, where the activated flux …

Influence of Center Cut Geometry and Power Law Index on the Free Vibration of Functionally Graded Shells
Abstract: This study explores the influence of power law variations and center cut geometries on the vibrational characteristics of functionally graded material (FGM) shells using finite element analysis (FEA). Stainless steel-alumina oxide (Al2O3) composites serve as the FGM, offering a unique blend of ceramic heat resistance and metallic toughness. Power law functions within APDL tailor material properties across the shell thickness. The research investigates vibrations under various boundary conditions (CCCC, CCFF, …

Machinability and Reliability Analysis of Al6063–Al2O3 Metal Matrix Composites Using Image-Based Flank Wear Evaluation
Abstract: This study explores the machinability and reliability characteristics of Al6063–Al2O3 metal matrix composites (MMCs) as analogues for polymer–metal hybrid composite systems, focusing on their potential use in lightweight structural and metal matrix composite-integrated applications. The composite specimens were fabricated through stir casting with 3% and 9% Al2O3 reinforcements, followed by mechanical characterization that confirmed significant enhancements in hardness and strength compared to unreinforced Al6063. Machining experiments were performed using a …
