An analytical review on Spark Plasma Sintering of metals and alloys: from processing window, phase transformation, and property perspective

C.P titanium/Ti–6Al–4V joint by spark plasma welding: Microstructure and mechanical properties

“…Considering the type of heterogeneous samples, different reactions may cause the development of the connection. For example, in the Al–Mg and zirconia connection, Al and Mg atoms react with the grain boundary phases of zirconia and zirconia itself (ZrO 2 ), leading to the development of the connection [ [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] ].…”

“…where they are absorbed. Thus, the contraction of pores is associated with the migration from the center of the gravity of the grains towards the boundary plane [ [37] , [38] , [39] , [40] ].…”

Electrochemical Performance and Microstructure Evolution of a Quasi-Solid-State Lithium Battery Prepared by Spark Plasma Sintering

“…8−13 From this aspect, the spark plasma sintering (SPS) technique can achieve high densification of powder samples in a short period and achieve intimate solid−solid interface contact. 14,15 SPS has shown unique advantages in preparing solid-state electrolytes and composite cathodes and anodes for solid-state lithium batteries. In an early work, Takeuchi et al prepared different composite cathodes, such as LiFePO 4 /C, Li 1.05 Mn 1.95 O 4 /C, and LiNi 0.8 Co 0.15 Al 0.05 O 2 /C, by SPS, achieving close combination between the electrode active materials and carbon additives, significantly improving their rate capability and overall electrochemical performance.…”

“…Therefore, ensuring the continuous network between solid-state electrolytes and electrode materials in batteries is essential to realizing the rapid conduction of lithium ions and electrons. At the same time, good interface contact between the composite electrode and the solid-state electrolyte is also necessary to reduce the interface impedance, minimize the diffusion barrier for lithium ions, and improve the overall electrochemical performance of solid-state lithium batteries. − From this aspect, the spark plasma sintering (SPS) technique can achieve high densification of powder samples in a short period and achieve intimate solid–solid interface contact. , SPS has shown unique advantages in preparing solid-state electrolytes and composite cathodes and anodes for solid-state lithium batteries.…”

Electrical and Heat Distributions and Their Influence on the Mass Transfer during the Flash Spark Plasma Sintering of a Cu/Cr Nanocomposite: Experiments and Numerical Simulation

“…Another creative solution that has been considered for the manufacturing of these nanocomposites is spark plasma sintering (SPS). Several investigations have demonstrated that materials fabricated using this technology exhibit few microstructural changes and have improved mechanical, electrical, and thermal characteristics compared with those of the components produced using other approaches [ 4 , 12 , 13 , 14 , 15 , 16 ].…”
