“…It should be noted that the obtained results can be correlated with the results obtained at the schemes of compaction with the alternative source of the process intensifiers as ultrasound, electric or magnetic pulses [43,[85][86][87][88][89][90][91][92][93]. In all of the cases, the better results can be achieved for the materials of transition metals group (Fe, Cr, Ni) that have an uncompensated spin in compounds for the formation of an adhesive bond.…”

A Cold-Pressing Method Combining Axial and Shear Flow of Powder Compaction to Produce High-Density Iron Parts

Highly performance methods for cold pressing (cold die forging) of preforms from iron powder with subsequent heat treatment and producing ready parts made of powder are described in the paper. These methods allow fabricating parts with smooth surfaces and improved mechanical characteristics—porosity, tensile strength. Application of the traditional design set-up with a single-axial loading is restricted to high stresses in the dies to deform the preforms that lead to cracks formation. New powder compaction schemes by applying active friction forces (shear-enhanced compaction) make it possible to unload dies and produce high-quality parts by cold pressing. The scheme allows moving the die in the direction of the material flow with a velocity that exceeds the material flow velocity.

“…Beyond these studies, there are many others, including in their title or in the abstract of the word “nano”, but referring to the development of zirconia-based products (also including zirconia composites) with grain size generally much higher than 100 nm [9,12,13,14,18,20,21,22,24,34,40,49,51,53,54,57,60,61,65,68], following conventional processing routes or innovative routes, such as one of the latest innovations in shaping techniques, such as the magnetic pulsed compaction [8], or reporting no information on the final grain size [7,11,12,55].…”

Nanostructured Zirconia-Based Ceramics and Composites in Dentistry: A State-of-the-Art Review

et al. 2019

View full text Add to dashboard Cite

The objective of this paper is to review the current knowledge on the development of nanostructured zirconia-based ceramics and composites suitable for application in dentistry. Isi Web of Science, Science Direct, Scientific.net databases, and Google were searched electronically for the period of 1980 to the present, matching the keywords “nano” with the keywords: “Zirconia, ZrO2, Y-TZP, and dental, dentistry”. A total of 74 papers were found, with the majority coming from Asia, indicating a more active scientific interest on the topic in this geographic area, followed by Europe, South America, and North America. The research shows, even though the scientific activity on nanostructured ceramics was intense in the last fifteen years, the development of fully dense zirconia-based nanoceramics is yet at an initial stage, most of all from the point of view of the clinical applications. It has been demonstrated that nanostructured ceramics can show improved properties because of the reduction of the grain size to the nanoscale. This is also true for zirconia-based nanoceramics, where some improvements in mechanical, optical, as well as resistance in low-temperature degradation have been observed. Potential applications of this class of material in the dental field are discussed, summarizing the results of the latest scientific research.

“…Therefore, more homogeneous distribution of components will be provided during compaction. One of the potential methods is the magnetic pulse compaction (MPC), which is based on transformation of an electric energy pulse into a mechanical powder compacting impact [15][16][17][18][19]. The impact rise time is about hundreds of microseconds, which provides compaction pressure in the range 1-5 GPa and the powder particle displacement rate in the order of 10-100 m/s.…”

Structural, Mechanical, and Tribological Characterization of Magnetic Pulse Compacted Fe–Cu Bimetallic Particles Produced by Electric Explosion of Dissimilar Metal Wires

Bimetallic 73 wt.% Fe–Cu nanoparticles have been produced using electric explosion of two immiscible metal wires and then consolidated into disks using magnetic pulse compaction. The compacted disks have been characterized for phase composition, mechanical strength, and high-temperature steel ball-on-disk sliding friction. The sample possessed good flexural and compression strength. Friction and wear reduction were observed during sliding test at 400 °C, which was explained by intense tribosynthesis of cuprospinel CuFe2O4 nanoparticles, which served to reduce adhesion between the ball and disk.
