This unit deals with the selection and fabrication of HMMC (Al6063-10SiC-5B4C-Mg) constituents by extensive biography review and satisfactory fabrication design. Researchers have promoted an extensive collection of Al6063 composites employing organic and inorganic reinforcements. The fundamental purpose of the broken-up stages is to constrain the metal matrix in a relevant capacity to strengthen the properties of the base materials. In the case of Al6063, the reinforcement weighty subject matter in the composite varies from 5 wt.% to 30 wt.%. Diverse classes of reinforcements had sought to integrate and operate in the composite formulation as hybrid reinforcements. This chapter further discusses the comprehensive development stages of 84% wt of Al 6063, 10% wt of SiC, 5% wt of B4C with 1% wt of Mg hybrid metal matrix composite (HMMC) through the stir casting approach. During the stir casting process, the melting action of the material emanates numerous gases and residuals apart from the expected composite. The residuals have numerous environmental concerns, which require discussion since some of the vapors and substantial waste can lead to detrimental effects on the environment in terms of air and soil pollution.

A comparative study on the effect of adding molybdenum di-sulphide (MoS2) powders of diameters 40 m, 90 nm size into an ultrasonic vibration induced dielectric liquid of electrical discharge machining (EDM) process is attempted. Discharge duration, peak current, gap voltage are selected as input variables and their impact is assessed using pulse train, discharge energy, material removal rate (MRR) and surface integrity which are considered as outcome measure. The outcome measures of powder mixed dielectric (PMD) are compared with that of pure dielectric. Through pulse trains, a new phenomenon of partial discharge is identified. The incidence of partial discharge are assessed using scanning electron microscope (SEM) images. By varying the discharge duration, peak current and gap voltage, the discharge energy reduces in contrast to pure dielectric by 4%, 21.01%, 8.35% respectively for 40 m diameter PMD and 10%, 27.29%, 17.99% respectively for 90 nm diameter PMD. The increase of peak current and gap voltage magnitudes cause the discharge energy to rise whereas discharge energy drops with growing magnitudes of discharge duration. Compared to the pure dielectric, the PMD produced enhanced MRR for similar discharge energy levels. The peak current has shown greater influence on MRR than discharge duration and gap voltage. In comparison with pure dielectric, the machining performance has improved by 21% for 40 µm diameter PMD, whereas 84.21 % for 90 nm diameter PMD. At higher discharge parameters, better surface topography is produced in PMD than pure dielectric.

“…By employing compacted electrodes, particles during the machining process will be settled on the material surface and limit the microcracks, voids, recast layer, and so forth [1][2][3]. The electrical discharge machining process guarantees legitimate carbonation and surface heattreatment, and a superior material hardness was acquired with an elevated peak current and reduced duty factor [4]. The electrodischarge machining of each nonconductive workpiece relies upon large variables.…”

Electrical discharge machining is a thermo-physical-based material removal technique. 25 combinations of process variables were formulated with the aid of Taguchi technique for EDM of adsorbed Si3N4–TiN. Machining variables like pulse current, pulse-on time, pulse-off time, dielectric pressure, and spark gap voltage varied, and impact of each variables on the performance metrics (MRR, EWR, SR, ROC, θ, CIR, and CYL) was assessed. MCDM strategies like grey relational analysis and TOPSIS are utilized to find out the ideal arrangement of machining parameters to achieve most acute productivity of the multitude of reactions. Likewise, metaheuristic algorithm in particular GRA combined with teaching-learning-based optimization algorithm is utilized for getting global optimized input factors. Important factors like pulse current, pulse-on time, and spark gap voltage characteristically affect the outputs. It is recognized that the pulse-on time and the pulse current are the most significant input factors than others. The ideal machining parameters in view of GRA and TOPSIS techniques for acquiring better output factors are I, 12 amps; PON, 7 μsec; POFF, 4 μsec; DP, 12 kg/cm2; and SV, 36 volts.
