spark plasma sintering (sps) method, as plasma activated sintering, is a method applicable for rapid sintering of metals and ceramics. owing to the advantage of rapid heating, the alumina ceramics obtained by sps have a grain size and density comparable to those of hot pressed ones. the increase of densification rate may be related to some difference in ion transport characteristics. this study...

To achieve value-added utilizations of plantation timbers, eucalyptus veneer/high-density polyethylene film composites were prepared, with process-factors (PF) (hot-pressing temperature, HT; hot-pressing duration, HD; hot-pressing pressure, HP; HDPE-film content, HC) and composite-properties (CP) (water-resistant bonding-strength, BS; modulus of rupture, MOR; modulus of elasticity, MOE) investi...

Cu/Ti3SiC2/C/BN/GNPs nanocomposites were prepared by vacuum hot-pressing (HP) sintering and hot isostatic pressing (HIP) sintering methods. Microstructures, mechanical and tribological properties of Cu/Ti3SiC2/C/BN/GNPs nanocomposites were investigated. Microstructures were examined by optical microscopy (OM), X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical properties...

Abstract Alumina whisker reinforced zirconia ceramic composite was prepared by both hot oscillatory pressing (HOP) and conventional (HP). The results show that compared with HP, HOP can significantly increase the final density densification rate of material. Analysis kinetics reveals predominant mechanism transits from grain boundary sliding in beginning to diffusion later stage. main effect os...

In this work, low volume reinforcement ex-situ Ti-B4C composites were produced using two different routes: conventional powder metallurgy (PM) and hot-pressing (HP). The effect of phases processing method on corrosion tribocorrosion behaviour studied. Composites processed by PM lost the typical passive Ti matrix, while HP presented similar to unreinforced Ti. Tribocorrosion tests showed that bo...

Mn-doped tetrahedrites Cu12-xMnxSb4S13 (0.1 ≤ x 0.4) were synthesized by mechanical alloying (MA) and sintered hot pressing (HP). A single tetrahedrite phase was MA without post-annealing, it stable any changes after HP. The hot-pressed specimens had a relative density higher than 98.6%. lattice constant of the samples increased compared to that undoped Cu12Sb4S13, but no significant change in ...

High-performance Sr0.6K0.4Fe2As2 (Sr-122) tapes have been successfully fabricated using hot pressing (HP) process. The effect of HP temperatures (850-925°C) on the c-axis texture, resistivity, Vickers micro-hardness, microstructure and critical current properties has been systematically studied. Taking advantage of high degree of c-axis texture, well grain connectivity and large concentration o...

This study addresses the fabrication of nanocrystalline Fe–Co–Ni alloy using two operations: mechanical alloying (MA) of elemental powders and hot pressing (HP). The evolution of the phase composition and structure of the powder particles after MA was investigated. Ball milling with rotation speed 700 rpm for 15–20 min allows the production of a bcc Fe-based supersaturated solid solution. Durin...
