“…The increase in CP, S.Temp, and ST increases the density of the AA8079-15 wt.%B 4 C composites. For AA8079-15 wt.%B 4 C composites, maximum density of 3.45 g/cm 3 was obtained at CP of 500 MPa, S.Temp of 575 • C, and ST of 3 h. It could be understood that an increase in CP, S.Temp, and ST enhances the density of the AA8079-B 4 C composites. This is due to the fact that diffusion of particles and decrease in porosity occurred; it results in improved density as reported by Patel et al [27].…”

“…The increase in CP, S.Temp, and ST increases the density of the AA8079-5wt.%B4C composites. For AA8079-5wt.%B4C composites, maximum density of 2.96 g/cm 3 was attained at CP of 500 MPa, S.Temp of 575 °C, and ST of 3 h. Densification is proportional to CP, S.Temp, and ST. The rate of dispersal enhances, while increase in S.Temp offers good densification at high temperature.…”

“…The increase in CP, S.Temp, and ST increases the density of the AA8079-10 wt.%B 4 C composites. For AA8079-10 wt.%B 4 C composites, maximum density of 3.25 g/cm 3 was obtained at CP of 500 MPa, S.Temp of 575 • C, ST of (1, 2, and 3 h). Enhancement in ST offers much time for pore closure in the matrix; henceforth, densification is perceived to rise with the rise in ST. At 575 • C, the density enhances due to a decrease in pores.…”

“…By following this method (PM) various kinds of materials can be easily mixed to attain unique properties [2]. PM is a frequent and fast developing technology, taking up all metallic and alloy materials and a widespread variability of dimensions [3]. Compared to other conventional fabrication methods, the PM route is recognized to be capable in the fabrication of aluminum alloy based MMC [4].…”

In this paper, Al-Fe-Si-Zn-Cu (AA8079) matrix composites with several weight percentages of B4C (0, 5, 10, and 15) were synthesized by powder metallurgy (PM). The essential amount of powders was milled to yield different compositions such as AA8079, AA8079-5 wt.%B4C, AA8079-10 wt.%B4C, and AA8079-15 wt.%B4C. The influence of powder metallurgy parameters on properties’ density, hardness, and compressive strength was examined. The green compacts were produced at three various pressures: 300 MPa, 400 MPa, and 500 MPa. The fabricated green compacts were sintered at 375 °C, 475 °C, and 575 °C for the time period of 1, 2 and 3 h, respectively. Furthermore, the sintered samples were subjected to X-ray diffraction (XRD) analysis, Energy Dispersive Analysis (EDAX), and Scanning Electron Microscope (SEM) examinations. The SEM examination confirmed the uniform dispersal of B4C reinforcement with AA8079 matrix. Corrosion behavior of the composites samples was explored. From the studies, it is witnessed that the rise in PM process parameters enhances the density, hardness, compressive strength, and corrosion resistance.

In modern technology, revolution plays a significant role in improving technology day by day, qualitatively and quantitatively. A new series of Al-Si-In-Sn quaternary alloys was fabricated through powder metallurgy (PM) route. In PM, density and porosity of the final product are strongly dependent on the sintering process. In order to increase the density, we have proposed hybrid phase sintering (HPS), which belongs to liquid phase sintering category. HPS is a combination of solid phase sintering and liquid phase sintering, in which two or more elements take part in solid phase sintering and two or more elements take part in liquid phase sintering to achieve full relative density. Therefore, HPS is only applicable for quaternary or high entropy alloys. We achieved 97.67 % and 96.33 % relative densities in a new series of Al100-xSixIn6Sn10 (x  12, 16) quaternary alloys using HPS at 600 C in tubular furnace with an argon atmosphere. We also observed that one parameter of PM affects all other parameters of PM. Therefore, we have tried to express the effect of the parameter in the form of a PM super hexagon.
