Carbon nanotubes (CNTs) are promising reinforcements for fabricating aluminum (Al) matrix composites with outstanding properties. The understanding of the consolidation process of CNT–Al composite powders plays a significant role in achieving high performances of bulk composites. In this study, an advanced consolidation technique of spark plasma sintering (SPS) was used to fabricate CNT–Al comp...

The coating of hollow alumino-silicate microspheres or cenospheres with thin layers of Cu by means of vibration-assisted magnetron sputtering yields a starting material with considerable potential for the production of new types of metal matrix syntactic foams as well as optimized variants of conventional materials of this kind. This study introduces the coating process and the production of ma...

In this work, we present experimental studies for the processing of TiO2/ TiCxO1−x Nanoceramic Composite. This paper reports the synthesis of TiO2/ TiCxO1−x composite with Ti/C ratio 50:30 via spark plasma sintering route (SPS). The sinterability, microstructure and mechanical properties of the SPS processed sample was optimized with considering time and temperature. TiCxO1−x was reinforced in ...

Based on precursor powders with a size of 200-300 nm prepared by the low-temperature solid-state reaction method, phase-pure YMnO₃ ceramics are fabricated using spark plasma sintering (SPS). X-ray diffraction (XRD) and scanning electron microscopy (SEM) reveal that the high-purity YMnO₃ ceramics can be prepared by SPS at 1000 °C for 5 minutes with annealing at 800 °C for 2 h. The relative densi...

Despite the growing interest in spark plasma sintering (SPS) of uranium dioxide, its mechanisms have yet to be studied great detail. Herein we propose a direct method calculate apparent activation energy for densification, Qact, and stress exponent, n, SPS nearly stoichiometric UO2. A set experiments performed at different heating rates (CHR) pressures levels allowed us Qact respectively, thoug...

Bacterial infection and stress shielding are important issues in orthopedic implants. In this study, Ag element was selected as an antibacterial agent to develop Ti-40Nb-10Ag alloy by spark plasma sintering (SPS). The microstructure, phase constitution, mechanical properties, microhardness, properties of the sintered alloys with different temperatures were systematically studied X-ray diffracti...

Ultrafine-grained Al matrix nanocomposites, reinforced with Al2O3 nanoparticles, were produced from milled powders, either by equal channel angular pressing (ECAP), at room or high temperature, without back pressure, spark plasma sintering (SPS). Their microstructures, mechanical properties (compression, hardness, and sliding wear), thermal stabilities (thermally induced softening cracking) com...
