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.
