“…However, due to the difficulty of heat dissipation, the cooling time of parts produced by SEBM additive manufacturing conditions is too long, which is prone to element segregation and defects. In the study of Soroush et al [111], copper-chromium alloy powder was used for SEBM additive manufacturing. It is found that there are chrome-rich spheres (<1 µm) embedded by Cu matrix in the microstructure of formed parts.…”

With the development of the aerospace and automotive industries, high heat exchange efficiency is a challenge facing the development of various industries. Pure copper has excellent mechanical and physical properties, especially high thermal conductivity and electrical conductivity. These excellent properties make pure copper the material of choice for the manufacture of heat exchangers and other electrical components. However, the traditional processing method is difficult to achieve the production of pure copper complex parts, so the production of pure copper parts through additive manufacturing has become a problem that must be overcome in industrial development. In this article, we not only reviewed the current status of research on the structural design and preparation of complex pure copper parts by researchers using selective laser melting (SLM), selective electron beam melting (SEBM) and binder jetting (BJ) in recent years, but also reviewed the forming, physical properties and mechanical aspects of pure copper parts prepared by different additive manufacturing methods. Finally, the development trend of additive manufacturing of pure copper parts is also prospected.

“…Due to a unique combination of thermal, electrical, and mechanical properties as well as being corrosion resistant under applied high-voltage, such materials have found specific use as the electrodes in vacuum interrupters of high-voltage electric circuits [7]. New approaches of powder metallurgy such as additive manufacturing technologies [8][9][10], spark plasma sintering (SPS) [3,4,11], self-propagating hightemperature synthesis (SHS) [5], and high energy ball milling (HEBM) [1,3,4,[11][12][13][14][15] permit control of the microstructure of such pseudo-alloys, and hence significantly improve their properties [16][17][18][19][20][21]. For example, by optimizing the parameters of HEBM, one may obtain composite nanostructured particles with different sizes of the metal constituents with the formation of supersaturated solid solutions [3,8,[13][14][15]22], which cannot be produced by conventional methods.…”

Spark plasma sintering (SPS) is widely used for the consolidation of different materials. Copper-based pseudo alloys have found a variety of applications including as electrodes in vacuum interrupters of high-voltage electric circuits. How does the kinetics of SPS consolidation for such alloys depend on the heating rate? Do SPS kinetics depend on the microstructure of the media to be sintered? These questions were addressed by the investigation of SPS kinetics in the heating rate range of 0.1 to 50 K/s. The latter conditions were achieved through flash spark plasma sintering (FSPS). We also compared the sintering kinetics for the conventional copper–chromium mixture and for the mechanically induced copper/chromium nanostructured particles. It was shown that, under FSPS conditions, the observed maximum consolidation rates were 20–30 times higher than that for conventional SPS with a heating rate of 100 K/min. Under the investigated conditions, the sintering rate for mechanically induced composite Cu/Cr particles was 2–4 times higher compared to the conventional Cu + Cr mixtures. The apparent sintering activation energy for the Cu/Cr powder was twice less than that for Cu–Cr mixture. It was concluded that the FSPS of nanostructured powders is an efficient approach for the fabrication of pseudo-alloys.
