In this study, indium (In)- and gallium (Ga)-doped zinc oxide (ZnO) ceramics, [Zn(1−x−y)GaxIny]O (x = 0, 0.02; y 0.005, 0.01, 0.02), were fabricated via spark plasma sintering (SPS) at 1423 K. Crystal structure microstructural analyses conducted to confirm the solubility of dopants understand correlations between crystallographic phases various compositions. It was confirmed that Ga 0.005) prom...

The results of X-ray spectral microanalysis W-Ni-Fe pseudo-alloy, obtained from electroerosive powders, are presented. Consolidation the powders was carried out by method spark plasma sintering using SPS 25-10 system. Using an EDAX energy-dispersive analyzer built into a Quanta 600 FEG scanning electron microscope, characteristic spectra were at various points on sample surface and along transv...

This work aims to explore WC-G201 high entropy cemented carbides properties fabricated by spark plasma sintering with AlCoCrFeNiTi0.2 and WC as binder phase hard respectively. powder were mixed at the mass ratio of 5: 95, 10: 90 15: 85 respectively, then via SPS 1300℃ for 5min. The results show that has good wettability WC, increase content, hardness alloy decreases gradually, fracture toughnes...

In this study, composite samples of WE43 (Mg-4Y-3RE-Zr) reinforced with nano-B4C particles in different ratios (0.5 and 2 wt.%) were prepared by spark plasma sintering (SPS). The powders mixed a 3-dimensional ball mill at 300 rpm. then hot pressed under 35 MPa pressure 525 °C for 6 min. XRD FESEM-EDS instruments used to characterize the samples. Microhardness wear tests performed designate mech...

Abstract In this work, novel 3 mol% yttria tetragonal zirconia polycristalline (3YTZP) ceramic composites with boron nitride nanosheets (BNNS) are investigated for the first time. Highly densified 1 and 4 vol% BNNS were obtained by spark plasma sintering (SPS) after synthesis using a solution exfoliation method dispersion into powder ultrasonication. The presented homogeneous distribution throu...

With the increasing acceleration of three-dimensional (3D) printing (for example, powder bed fusion (PBF)) metal alloys as an additive manufacturing process, a comprehensive characterization 3D-printed materials and structures is inevitable. The purpose this work was to test highly densified produced from gas-atomized pre-alloyed metallic powders, namely 316L, Ti6Al4V, AlSi10Mg, CuNi2SiCr, CoCr...

At present, metallic glasses are evaluated as alternative reinforcements for aluminum matrix composites. These composites produced by powder metallurgy via consolidation of glass-aluminum mixtures. In most studies, the goal has been to preserve glassy state reinforcement during consolidation. However, it is also interest track structure evolution these when partial interaction between and glass...
