“…Also, magnesium (1% i.e., about 10 g) is mixed to reduce the surface tension of the molten material during stirring. [21][22][23][24] After that, the slurry is poured into a preheated mould (at 300°C for 2h). 25 After solidification of the casting, it is taken out from the mold to prepare specimens for testing/characterization as per ASTM standards (Figure 2).…”

The present work reports the impact of granite marble powder (GMP) and SiC on the physical, microstructural, and mechanical characterization of the hybrid aluminium-based metal matrix composite (AMC). Al-4032/SiC/GMP composites with 4, 6, and 8 weight % of SiC and GMP (equal proportion) have been fabricated through stir casting. The impact on properties like density, porosity, ultimate tensile strength (UTS), elongation, microhardness, and impact strength were analyzed according to ASTM standards. A maximum of 1.07% increase in theoretical density and a maximum of 4.86% decrease in experimental density have been recorded for 8% reinforcement. Microstructure of the as-cast specimens were analyzed using optical microscope (OM), XRD (X-ray diffraction), and SEM (scanning electron microscope) equipped with EDS (energy dispersive spectroscopy). Owing to ceramic particles, mechanical properties like UTS, microhardness, and impact strength of the AMC got enhanced from 69.4 MPa to 146 MPa, 131.4 HV to 190.2 HV, and 22.4 J to 32.8 J, respectively.

“…Metallic materials can be manufactured by a wide variety of methods. Casting [1] is a first option, heating to the liquid state and pouring the liquid into moulds, or just cooling in a continuous way, to obtain rough bulk pieces. Parts with relatively precise dimensions can also be obtained working with small amounts of material poured on precise moulds [2].…”

Manufacturing metallic materials from elemental or alloyed powders is an option in many industrial processes. Nevertheless, the traditional powder metallurgy processing including furnace sintering is at times detrimental for the microstructure attained in the powders. Alternative sintering processes based on the use of electricity and the energy obtained by the Joule effect in powder particles can be quick enough to avoid microstructural changes. In particular, when the energy is stored in a capacitor and then discharged, the heating process is extremely quick, lasting milliseconds or even microseconds. This process, generally known as electrical discharge consolidation, has been applied to a wide variety of metallic materials, easily preserving the original microstructure of the powders. Both porous or homogeneous and highly densified material can be obtained, and without losing the desired properties of the consolidated material. A general overview of the process and applications, as well as the results obtained by different research groups around the world, have been reviewed in this manuscript.
