“…The sample was also wrapped in a graphite sheet, 0.2 mm thick. The sintering was done using a spark plasma sintering system (SPS) (Labox 650, Sinter Land, Japan) [27][28][29][30] under the following conditions: heating rate 50 • C/min, maximum temperature of 245 • C, pressure up to 50 MPa, residence time 5 min. The parameters of the SPS configuration and the device schema are shown in Reference [27].…”

A composite material based on polyethylene terephthalate (PET, about 1% by mass) and Al 85 Y 8 Ni 5 Co 2 metallic glass was obtained by mechanical alloying and consequent spark plasma sintering. The spark plasma sintering was performed at a temperature near to the super cooled liquid region of the metallic glass. Mechanical properties and the structural characterization of the composite material were obtained. It was conceived that composite samples (Al 85 Y 8 Ni 5 Co 2 /PET) have a better thermal conductivity in comparison with pure PET samples. The formation of the crystalline phases causes degradation of physical properties. It was calculated that the activation energy for crystallization of the Al 85 Ni 5 Y 8 Co 2 metallic glass is higher than that of the other types of metallic glasses (Mg 67.5 Ca 5 Zn 27.5 and Cu 54 Pd 28 P 18 ) used for composite preparation previously. This denotes a good thermal stability of the chosen metallic glass.

“…This method takes advantage of preventing surface oxidation of materials at high temperatures [5], evaporation of impurities during the process due to low partial pressure [6], providing conditions for performing in situ synthesis that require vacuum [7], consolidation under inert or reactive atmospheres [8], and pressure-assisted densification [9]. Additionally, it includes the unique benefits that come from the direct application of electric current in sintering [10]. The importance of this issue becomes even clearer by noticing that in all the different names that have been considered for this method such as field-assisted Handling Editor: P. Nash.…”

Copper and its alloys have been in the service of humankind earlier than any other metal throughout history. In the present review, all aspects of the SPS of copper and its alloys are comprehensively investigated, and their potential effects on the microstructure and properties of alloys are thoroughly reviewed. In this regard, the densification phenomenon during SPS treatment is fully investigated. The effects of raw powder characteristics involving particle size, contamination content, and powder morphology on the sinterability of these materials are examined. Then, the influence of SPS operation parameters consisting of pressure, heating rate, dwelling time, pulsed electrical current, electrical pulses pattern, sintering temperature, and sintering tooling on densification of these materials is extensively discussed. Furthermore, the microstructure evolution and grain growth behaviors during SPS are explored. In addition, current challenges and future perspectives of this field are addressed.

“…There are several ways to improve heat transfer (Bakthavatchalam et al, 2020). Material science and nanotechnology result in remarkable advancement in heat transfer (Abedi et al, 2016;Kuskov et al, 2021). Higher heat exchange potential along with the compact design are unique properties of microchannels (Akbari et al, 2016;Gravndyan et al, 2017).…”

The idea of using the compact device with higher heat transfer potential has encouraged researchers to use microchannels. Creating sinusoidal walls is a technique leading to better effectiveness and smaller size. In this study, the effects of discrete heat sources location on heat transfer and pressure drop are investigated, using graphene nanoplatelets/water inside a sinusoidal microchannel. For this, discrete heat sources are installed in a smooth microchannel (layout A) and compared with two sinusoidal-wall microchannels. In layouts B and C, the heating sources are installed above the convergent/diverging sections, respectively. Since the velocity and temperature gradients are higher in the converging region, the heat exchange and pressure drop for layout B are greater than other ones. In other words, installing heating sources in these regions with high-temperature gradient has a more obvious positive efficacy on heat exchange. For the best layout (B), although the heat exchange compared to the base layout (A) is 37.5% higher, the pressure drop and entropy generation are higher by 79% and 35.2%, respectively. By introducing a new figure of merit (FOM), it is found that layout B is in the desirable zone.
