: Due to their low weight, high strength and enhanced tribological properties, aluminium alloy composite materials are recognized globally after for highly scientific applications. Al7075 hybrid composite was created by using the sand mould process in an electric resistance furnace to reinforce aluminium oxide (Al 2 O 3 ) and boron carbide (B 4 C) particles. In this study, the mechanical behaviour of hybrid composites made of Al7075, Al 2 O 3 , and B 4 C with stable Al 2 O 3 contents of 2% and variable B 4 C weight percentages of 2% to 6% was examined. In both pure and cast specimens, the mechanical characteristics, such as tensile and compressive strength, hardness, and microstructure analysis, were assessed. In this study, the mechanical characteristics of the hybrid composites made from Al7075 alloy were experimentally studied and validated using the ASTM standard and FEA. The results showed that when hard ceramic particles (Al 2 O 3 /B 4 C) were added to a matrix alloy (Al7075), mechanical characteristics such as compressive strength and hardness improved while tensile strength was reduced. The static structural tensile test was successfully simulated in ANSYS. It was observed that both FEA results and analytical results were correlated.

In this study, we investigated the structural, optical, photoluminescence, and magnetic characteristics of pristine and Cr/Mn-doped ZnO nanoparticles prepared via the solution combustion method. The prepared nanoparticles exhibited a monophasic hexagonal structure. The successful incorporation of Cr/Mn elements into the ZnO lattice is reflected in the X-ray photoelectron spectroscopy, UV-vis. absorbance spectroscopy and Fourier-transform infrared spectroscopy measurements. Further, the photoluminescence intensity of ZnO nanoparticles changed upon Cr/Mn-doping due to the changed defect structure of nanoparticles. Furthermore, both pristine and Cr/Mn-doped ZnO nanoparticles revealed the ferromagnetic behaviour, wherein the doping of Cr/Mn enhanced the ferromagnetic characteristics. Overall, our results divulged that doping ZnO nanoparticles with appropriate combination of transition elements would leads to unearth fascinating optical and magnetic properties.

In this movement I utilized all around naturally known as two stages heat treatment called RRA is connected on AL 7075 composite to inspect the corrosion behavior. this procedure incorporates the different phases of warmth medicines incorporates, strengthening, high temperature pre-precipitation, counterfeit maturing (T6), retrogression and re-maturing. The examples are at first aged to 473o and then extinguished in water medium .the examples are additionally aged to 18hr, 22hr, 26hr separately .after this examples are warmed 230o, 250o 270o, 290o with various time interims 7 and 14 min individually to improve the quality of the material this procedure we call it as retrogression and re-aging. After this directed test and came to realize that by utilizing RRA strategy we can expand the quality of the material to most extreme degree. With this RRA methodology we can increase the corrosion resistance of the material to next level.

In this activity I used very familiarly known as two steps heat treatment called RRA is applied on AL 7075 alloy to examine the fatigue behavior. this process includes the various stages of heat treatments includes, annealing, high temperature pre-precipitation, artificial aging (T6), retrogression and re-aging. The specimens are initially heated to 473o & then quenched in water medium .the specimens are further heated to 18hr, 22hr, 26hr respectively .after this specimens are heated 230o, 250o, 270o, 290o with different time intervals 7 & 14 min respectively to enhance the strength of the material this process we call it as retrogression and re-aging .after this conducted experiment and came to know that by using RRA method we can increase the strength of the material to maximum extent.
