Spark plasma sintering as the prominent field‐assisted technique (FAST/SPS) is a novel technology for rapid, pressure‐assisted consolidation of powder materials. The main feature FAST/SPS direct Joule heating applied tooling. Tooling challenging part setup, which must withstand high pressure at elevated temperatures and ensure uniform temperature distribution in sintered part. This review looks standard tooling, specific tooling complex‐shaped parts, pressureless sintering. A particular...
The paper presents the results of study microstructure and selected properties spark plasma sintered Al matrix composites reinforced with 2 μm SiC particles. Composites contents 10, 20 30 wt % were prepared. sintering process was carried out by means an HP D 25–3 furnace, using two temperatures: 580 °C 600 °C. As reference material, pure under same conditions. a near full density 97–99% obtained. test did not show remarkable difference in particles at compacts consists uniform grains,...
This paper presents a comparison of surface morphology obtained after machining Inconel 718 by the conventional insert, Wiper insert and using cutting made Spark Plasma Sintering (SPS). The shape special was employing Wire Electrical Discharge Machining (WEDM). focuses on description topography turning in dry wet conditions. performed investigation included longitudinal tests range variable feeds. Surface measurements have been with application Nanoscan 855. analysis includes parametric...
A novel approach to developing high entropy alloys (HEAs) using spark plasma sintering (SPS) was explored in this work where a mix of commercial commodity powders like Ni625, CoCrF75, and 316 L used instead pre-alloyed avoiding the expensive pre-alloying steps mechanical alloying or gas atomizing. Three non-equiatomic HEAs, based on Co, Cr, Fe, Ni, Mo were designed developed by blending which sintered via SPS resulted single FCC phase after homogenization. The HEAs microstructurally...
This study introduces an innovative alloy design strategy by integrating HEAs principles to develop CoNi-based high entropy superalloys (HESAs). The powder of designed HESA produced using gas atomization and consolidated spark plasma sintering (SPS). validated CALPHAD mitigate detrimental phase precipitation segregation during production, material consolidation, post-processing heat treatments. CoNi-HESA with a calculated mixing 1.568R was successfully developed SPS. Optimization SPS...
In this work, (W,Ti)B2 films with different stoichiometric ratio Ti/W deposited on silicon and 304 stainless steel by radio frequency magnetron sputtering are presented. The coatings were from plasma spark sintered targets obtained the mixture of pure boron, tungsten titanium powders. It is shown that during sintering process using overstoichiometric boron a low content change WB2 to WB4 phase almost no secondary phases. Subsequently, impact properties investigated systematically, including...
Two different zirconium contents (0.45 and 0.60 wt.%) have been incorporated into a Fe-14Cr-5Al-3W-0.4Ti-0.25Y2O3 oxide dispersion-strengthened (ODS) steel in order to evaluate their effect on the final microstructure mechanical properties. The powders with targeted compositions were obtained by alloying (MA), subsequently processed spark plasma sintering (SPS) at two heating rates: 100 400 °C·min−1. Non-textured bimodal microstructures composed of micrometric ultrafine grains obtained....
Alloys based on magnesium are of considerable scientific interest as they have very attractive mechanical and biological properties that could be used to manufacture biodegradable materials for medical applications. Mechanical alloying is a suitable process obtain alloys normally hard produce it allows solid-state diffusion via highly energetic milling, producing fine powders. Powders obtained by this method can sintered into nearly net-shape products, moreover, their phase chemical...
The synthesis of MAX-based composites from Ti3SiC2-based and non-stoichiometric Ti/SiC powders was developed via field-assisted sintering technology/spark plasma (FAST/SPS) in vacuum at temperatures ranging 1350 to 1450 °C, with a heating rate 200 °C/min, holding time 1.5 15 min, compaction pressure 60 MPa. phase composition the analyzed using X-ray diffraction (XRD), while microstructure examined by means light microscopy (LM) scanning electron (SEM) energy dispersive X-Ray spectroscopy...
Spark plasma sintering has been used to successfully produce WC-6Co-xCr3C2, WC-6Co-xTaC (x = 0.2, 0.6, 1.0) and WC-6Co-xCr3C2-xTaC 0.1, 0.3, 0.5) cemented carbides. The spark sintered compacts were investigated by scanning electron microscopy, hardness tests fracture toughness tests. results compared an additives-free WC-6Co carbide consolidated under the same process parameters commercial ISO K10 inserts. By using Cr3C2 TaC additives, it is possible improve of WC-Co best combination (1936 ±...
