This study aims to optimize process parameters in Wire Electrical Discharge Machining (WEDM) for a hybrid Metal Matrix Composite (MMC) composed of aluminum alloy (Al 6351) reinforced with 6% graphite (Gr) and 4% silicon carbide (SiC). The MMC was fabricated using the squeeze casting technique, an L27 orthogonal array employed experimental design. Key WEDM parameters, including pulse-on time (P), pulse-off (Q), wire feed (R), spark voltage (S), tension (T), were systematically varied assess their impact on surface roughness (SR), material removal rate (MRR), dimensional deviation (DD), kerf (K). Gray relational analysis utilized determine optimal parameter settings based gray grade, while Fisher variance conducted evaluate significance individual parameters. A confirmation test validated findings, revealing that optimized setting (P3Q1R3S1T3) significantly improved MRR, SR, overall machining performance compared initial (P1Q1R1S1T1). Although minor variations observed DD kerf, optimization approach effectively enhanced key metrics. In addition, scanning electron microscopy x-ray diffraction analyses further characterize machined surfaces. provides systematic improving efficiency advanced MMCs, contributing precision industrial applications.

Purpose This paper aims to analyze the reflection characteristics of coupled waves in a functionally graded piezomagnetic medium, considering gravitational effects. The objective is understand how flexomagnetism, strain gradients and gravity influence wave behaviors. Design/methodology/approach study incorporates flexomagnetic effects, micro-inertia into constitutive governing equations develop comprehensive model for propagation. A secular equation motion derived, behavior five distinct reflected analyzed, specifically focusing on their energy ratios. Numerical solutions validate conservation, graphs illustrate variations with incidence angle. Findings Results demonstrate that functional grading significantly impact distribution reflections, altering dynamics dispersion Functional effects introduce complexity reflection, providing insights redistribution. Originality/value offers novel approach by integrating propagation models materials, unique under complex conditions.

Electrical Discharge Machining (EDM) is an advanced, non-conventional machining technique that relies on thermal energy to remove material from a workpiece. In EDM, removal occurs as result of intense heat generated by the movement electrons negatively charged cathode positively anode. This process leads both melting and vaporization An essential factor influencing EDM efficiency dielectric fluid, which significantly impacts outcomes such tool degradation, efficiency, surface finish electrode. industrial settings, hydrocarbon-based oils are preferred choice for fluids. However, when these break down, they emit harmful substances polycyclic aromatic hydrocarbons, benzene, carbon monoxide, dioxide, contributing environmental pollution posing health hazards. To enhance sustainability process, alternative fluids, including gas-based, water-based, emulsion-based options, have been explored. Notably, research has shown vegetable can serve effective environmentally friendly medium in EDM. study offers brief review various fluids used emphasizing their role improving sustainability. addition, assessment eco-friendly alternatives presented, highlighting potential make safer more responsible.

Multilayered composites are widely used in automobile components. The properties of multilayered mainly depend on processing parameters. In this investigation, Al/Ti were fabricated by accumulative roll bonding (ARB). influence rolling parameters including velocity (10 < v 20 r/min), cycle (7 cycles), and friction coefficient (0.08 µ 0.14) the evolution microstructure, grain refinement, variations hardness, tensile features examined. results microstructural characterization showed that layers became more discontinuous broken pieces Ti better distributed Al matrix when increased decreased. addition, structure revealed refinement after 7 th cycle. was refined 0.14 10 r/min. hardness strength values as When r/min, highest 520 MPa obtained maximum 76 HV 292 HV, respectively. Although fracture surfaces delamination different sizes dimples, a larger number dimples observed at higher velocities lower coefficients.
