“…Refined grains could be obtained by SPS owing to the shorter sintering time and lower sintering temperature in the process, which is beneficial to improve the sintering properties and comprehensive properties of the Cu matrix composites [59][60][61]. Numerous studies [62][63][64][65] have confirmed that the SPS-fabricated sample display significantly smaller mean grain sizes compared with the conventional sintered samples. Moreover, the number of cracks in the samples sintered by SPS is also greatly reduced due to its special heating method.…”

Copper matrix composites doped with ceramic particles are known to effectively enhance the mechanical properties, thermal expansion behavior and high-temperature stability of copper while maintaining high thermal and electrical conductivity. This greatly expands the applications of copper as a functional material in the fields of thermal and conductive components, including electronic packaging materials and heat sinks, brushes, integrated circuit lead frames, etc. So far, endeavors have been focusing on how to choose suitable ceramic components and fully exert the strengthening effect of ceramic particles in the copper matrix. This article reviews and analyzes the effects of preparation techniques and the characteristics of ceramic particles, including ceramic particle content, size, morphology and interfacial bonding, on the diathermancy, electrical conductivity and mechanical behavior of copper matrix composites. The corresponding models and influencing mechanisms are also elaborated in depth. This review contributes to a deeper understanding of the strengthening mechanisms and microstructural regulation of ceramic particle reinforced copper matrix composites. By more precise design and manipulation of composite microstructure can help to further improve their comprehensive properties and meet the growing demands in the fields of functional materials.

“…The latter method makes it possible to produce compounds of almost any metallic composition [1,23,24]. The established advantages of SPS over traditional technologies are as follows: (a) low sintering temperatures, (b) short sintering cycle times (minutes), (c) low power consumption (about 1/5 of HP), (d) uniform heating of the material, (e) control of the temperature gradient, (f) absence of sintering additives and plasticizers, (g) sintering of powders with a wide particle size distribution, (h) achieving maximum density of the material (up to 100% of theoretical), (i) one-stage sintering, and (j) cleaning of the particle surface under the influence of current.…”

To study the material based on the binary system Ti + Cu (50% atm), samples were produced from powders of commercially pure metals and additionally ground in a ball mill (final size about 12 µm) by spark plasma sintering. The following intermetallic phases were obtained in the materials: CuTi2, TiCu, and Ti3Cu4. The materials have a hardness of 363 and 385 HV (800 and 900 °C), a microhardness of 393 and 397 µHV, a density of 4.24 and 5.23 kg/m3, and resistance to corrosion in acids (weight gain + 0.002% after 24 h of testing according to ISO 16151 for a sample with 900 °C—the best result in comparison with steel 308, AA2024, CuA110Fe3Mn2). The hardness value varies due to the presence of pure metal agglomerates. The relationship between the temperature of spark plasma sintering and the characteristics of the material (material parameters improve with increasing temperature, segregation is reduced) is revealed.

“…However, it is still a challenge to fabricate high relative density and fine grain bulks, which are expected to show an enhanced performance. Appropriate additives, such as Cr, Co, Mn, Re, Al, Si, Sn, Zn, YSZ, and Y 2 O 3 , were suggested to refine the microstructure of tungsten alloys [ 8 , 25 , 26 , 27 , 28 , 29 , 30 ]. The alloys could also be enhanced by cold plastic deformation after annealing at lower temperatures [ 31 ].…”

Tungsten heavy alloy (WHA) is an ideal material employed for kinetic energy penetrators due to its high density and excellent mechanical properties. However, it is difficult to obtain ultrafine-grained tungsten alloy with excellent properties by traditional powder metallurgy method because of severe grain growth at a high sintering temperature with a long soaking time. In this study, the sintering behavior of tungsten alloys was studied at 800 to 1300 °C, and highly dense 93W-5.6Ni-1.4Fe (wt.%) WHA was successfully fabricated at a low temperature of 950 °C with a high pressure of 150 MPa by spark plasma sintering. The as-sintered tungsten alloy possesses a high relative density (98.6%), ultrafine grain size (271 nm) and high dislocation density (2.6 × 1016 m−2), which results in excellent properties such as a high hardness (1079 HV1). The high sintering pressure is considered to support an additional driving force for the sintering and lead to a low-temperature densification, which effectively limits grain growth.
