“…Moreover, the capabilities of FS combined with other FAST techniques are evolving in other interesting "flash-based methodologies" that have experienced great development as well. That is the case of Flash Spark Plasma Sintering (F-SPS), where pressure and pulsed currents are simultaneously applied, enabling the homogeneous and energetically efficient sintering (by different electrodes architectures) of both electric conductive and insulating materials [36,37,[84][85][86][87][88]. Contactless Flash Sintering (Contactless-FS) is another flash-based methodology.…”

Flash Sintering (FS), a relatively new Field-Assisted Sintering Technique (FAST) for ceramic processing, was proposed for the first time in 2010 by Prof. Rishi Raj’s group from the University of Colorado at Boulder. It quickly grabbed the attention of the scientific community and since then, the field has rapidly evolved, constituting a true milestone in materials processing with the number of publications growing year by year. Moreover, nowadays, there is already a scientific community devoted to FS. In this work, a general picture of the scientific landscape of FS is drawn by bibliometric analysis. The target sources, the most relevant documents, hot and trending topics as well as the social networking of FS are unveiled. A separate bibliometric analysis is also provided for Reaction or Reactive Flash Sintering (RFS), where not only the sintering, but also the synthesis is merged into a single step. To the best of our knowledge, this is the first study of this nature carried out in this field of research and it can constitute a useful tool for researchers to be quickly updated with FS as well as to strategize future research and publishing approaches.

“…This study investigates the sinter-forging in a stable grain size zone below 90% of densification [33]. Using the SPS sinter-forging moduli, we were able to reproduce the flash SPS curve [34]. This suggests the identified moduli were reactive enough to explain the sintering kinetics as fast as flash SPS.…”

“…In our previous studies [ 3 , 35 ], we discovered that using this technology can reduce the sintering time by 40 times and the energy consumption by more than 20 times while maintaining the same characteristics and microstructure. Several publications [ 36 , 37 , 38 ] have numerically modeled the FSPS process. However, the effects of a high heating rate and current density on the microstructural evaluation of these nanocomposites utilized in this approach are not well understood.…”

The nanocomposite Cu–Cr powder was consolidated by flash spark plasma sintering (FSPS), which involves applying an extremely rapid change in the electrical power passing through the bulk of the sample. It was demonstrated that an essentially fully dense material could be obtained in 15 s. Such short-term treatment typically preserves the nanostructured features of the material. However, investigation revealed a nonuniformity in the microstructure of the alloys obtained under such extreme conditions. To better understand the observed effects, the FSPS process was simulated. It was observed that a rapid change in the applied electrical power resulted in nonuniform distributions of current density and temperature along the body of the consolidated material. Specifically, the current density was higher on the periphery of the sample, and the temperature was higher in the middle. These findings explain the observed structural transformation during FSPS and suggest an optimization strategy to avoid microstructural nonuniformity.
