“…There are a large number of reviews describing in detail the fundamental process (related to parameters on atomic diffusion and kinetic mechanisms, etc.) of the SPS technique [ 3 , 10 , 23 , 25 , 40 , 41 , 42 ]. In its basic configuration, the SPS apparatus simultaneously applies a pulsed high DC current along with uniaxial pressure to densify powders or synthesize (and consolidate) new compounds.…”

Spark plasma sintering (SPS), also called pulsed electric current sintering (PECS) or field-assisted sintering technique (FAST) is a technique for sintering powder under moderate uniaxial pressure (max. 0.15 GPa) and high temperature (up to 2500 °C). It has been widely used over the last few years as it can achieve full densification of ceramic or metal powders with lower sintering temperature and shorter processing time compared to conventional processes, opening up new possibilities for nanomaterials densification. More recently, new frontiers of opportunities are emerging by coupling SPS with high pressure (up to ~10 GPa). A vast exciting field of academic research is now using high-pressure SPS (HP-SPS) in order to play with various parameters of sintering, like grain growth, structural stability and chemical reactivity, allowing the full densification of metastable or hard-to-sinter materials. This review summarizes the various benefits of HP-SPS for the sintering of many classes of advanced functional materials. It presents the latest research findings on various HP-SPS technologies with particular emphasis on their associated metrologies and their main outstanding results obtained. Finally, in the last section, this review lists some perspectives regarding the current challenges and future directions in which the HP-SPS field may have great breakthroughs in the coming years.

This study investigates the sintering mechanism of commercially pure Magnesium (Mg) using the Field Assisted Sintering Technique (FAST). FSEM and XRD analysis identified four distinct bonding and sintering mechanisms influenced by particle geometry, residual stress, and microstructure developed through mechanical milling. XRD analysis demonstrated variations in crystallite size and lattice micro-strain with increasing milling time. The combination of mechanical milling and FAST exhibited significant effects on the microstructural and mechanical properties of Mg powders, with the Mg36 sample displaying promising strength and hardness.

“…Mechanical pressure is applied to remove pores, further enhancing the densification process [1,4]. Despite the numerous advantages of SPS, some researchers have reported issues such as non-uniform densities and microstructures [9][10][11]. Density variations, with the core exhibiting higher density than the outer regions, have been observed [12].…”

A modification to the conventional spark plasma sintering (SPS) process was undertaken to allow edge-free deformation of grains longitudinally to the loading axis in a process termed spark plasma texturing (SPT). The resulting Al7075 SPT compact was compared to SPSed Al7075 in terms of densification behaviour, microstructural evolution, and mechanical properties. The result reported herein highlights the unique benefits of the SPT technique and potential application in the manufacturing of advanced materials.
