“…For instance, increasing the heating rate up to a specific value would increase the relative density of nickel alloys by reducing the amount and size of the porosities, resulting in better particle bonding. However, increasing the heating rate more than a critical value (175 o C/min in nickel alloy) has induced lower densification [45].…”

As of today, metals and alloys are widely utilized as structural, mechanical, electrical, and magnetic materials in every aspect of technology and industry. The complexity and diversity of metals applications emphasize the need for a new production method to quickly and easily manufacture metallic components. Spark plasma sintering as a new solidstate sintering method has been recently developed to respond to these needs. Up to now, numerous papers and researches have been published in the field of spark plasma sintering and its ability to manufacture metallic samples. Density is a significant property that has a great influence on the physical, mechanical, and functional properties of metallic parts. To the best of our knowledge, there is no concrete paper that reviews the densification behavior of metals and alloys during spark plasma sintering and the effect of its parameters on the density of metallic samples. As a result, this article dedicated to addressing this need. In this mini-review, after a short description of spark plasma sintering method, the effects of each sintering parameters on densification behavior of metals and alloys are studied, and possible physical and microstructural factors which have the effect of densification behavior of metallic samples at various sintering conditions are reviewed. Finally, the recent advances in finite element modeling, which study the temperature and stress inhomogeneity in the SPS process, have been reviewed in this paper.

“…long sintering time may lead to a grain growth, which may be overcome with spark plasma sintering. This novel technique prepares composites with high densities with relatively low sintering times [58][59][60]. Ridvan et al [61] stated that in spark plasma sintering of Al-nano SiC composite, the sintering temperature plays vital role in densification of composites.…”

Metal Matrix Composites are developed in recent years as an alternative over conventional engineering materials due to their improved properties. Among all, Aluminium Matrix Composites (AMCs) are increasing their demand due to low density, high strength-to-weight ratio, high toughness, corrosion resistance, higher stiffness, improved wear resistance, increased creep resistance, low co-efficient of thermal expansion, improved high temperature properties. Major applications of these materials have been in aerospace, automobile, military. There are different processing techniques for the fabrication of AMCs. Powder metallurgy is a one of the most promising and versatile routes for fabrication of particle reinforced AMCs as compared to other manufacturing methods. This method ensures the good wettability between matrix and reinforcement, homogeneous microstructure of the fabricated MMC, and prevents the formation of any undesirable phases. This article addresses mainly on the effect of process parameters like sintering time, temperature and particle size on the microstructure of aluminum metal matrix composites.

“…To overcome this problem, properties should be improved by adding hard ceramic particle thereby strengthening second phase. The synergic effect of its incredible damage tolerance as a matrix and reinforcement could form metal matrix composite (MMC) with outstanding properties [6]. Generally, Ni base alloys exhibit poor machinability that leads to poor quality and production requirement [7].…”

In this investigation, Ni-Co-Cr-SiC composites with various weight percentages were manufactured via powder metallurgy (PM) route. The compositions of the composites are Ni-10%Co-5%Cr, Ni-10% Co-5%Cr-4%SiC, Ni-10%Co-5%Cr-8%SiC and Ni-10%Co-5%Cr-12%SiC. The powders were mixed using planetary ball mill for a period of 10 h. The ball milled powders were subjected to X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) analysis. By utilizing 150 kN hydraulic press with appropriate punch and die the ball milled powders were compacted as a cylindrical billets. The green compacts were sintered in a tubular furnace at two different temperatures 1000°C and 1200°C for3 h. The characterization examination namely XRD, SEM and Energy Dispersive Analysis (EDAX) was made on the sintered samples. Unreinforced Ni-Co-Cr exhibits higher sinterability at both sintering temperature. The sintering temperature and reinforcement weight percentage effect on the mechanical properties and corrosion behavior of the composites were examined. From these investigations, the mechanical properties and corrosion resistance of the composites were enhanced while increasing the sintering temperature and SiC weight percentage in the Ni-Co-Cr super alloy matrix.
