A wet-chemical method combined with spark plasma sintering was used to prepare a W-Y2O3 alloy. High-temperature tensile tests and nano-indentation microhardness were characterize the mechanical properties of After He-ion irradiation, fuzz He bubbles observed on irradiated surface. The irradiation embrittlement reflected by crack indentations formed during tests. phase transformation from α-W γ-W investigated X-ray diffraction (XRD) transmission electron microscopy (TEM). Polycrystallization...
The EAST lower divertor features a partially implemented flat-type structure, and visible damage has been observed, particularly at the outer horizontal target location after plasma operations. This study conducts detailed analysis of to target. findings reveal instances plastic deformation, cracking, even tungsten flake detachment specific locations on Furthermore, different degrees recrystallization are identified in plates operations, with more pronounced effect closer surface plates....
Ultra-fine tungsten carbide (WC) powder refers to WC powders with a particle size between 100 500 nm. Researchers have improved the comprehensive properties of WC-based cemented carbides by preparing ultra-fine powders. Because preparation and application nano-scale powders, ultrafine-grain excellent hardness wear resistance been successfully produced. In this paper, methods are divided into solid-phase, liquid-phase, vapor-phase according state raw materials (i.e., W or C source). The...
Abstract Pure W and W-(2%, 5%, 10%) Lu alloys were manufactured via mechanical alloying for 20 h a spark plasma sintering process at 1,873 K 2 min. The effects of doping on the microstructure performance investigated using various techniques. For irradiation analysis, thermal desorption spectroscopy (TDS) measurements performed from room temperature to 1,000 infrared with heating rate 1 K/s after implantations He + D ions. TDS conducted investigate retention behavior. Microhardness was...
Abstract Dense W and W–Zr composites reinforced with Sc 2 O 3 particles were produced through powder metallurgy subsequent spark plasma sintering (SPS) at 1700 °C 58 MPa. Results showed that the W–1vol.%Zr/2vol.%Sc exhibited optimal performance best relative density of up to 98.93% high Vickers microhardness approximately 583 Hv. The thermal conductivity W–Zr/Sc decreased initially then increased as Zr content increased. moderate alloying element could combine well grains form a solid...
Highly uniform oxide dispersion-strengthened materials W–1 wt % Nd2O3 and CeO2 were successfully fabricated via a novel wet chemical method followed by hydrogen reduction. The powders consolidated spark plasma sintering at 1700 °C to suppress grain growth. samples characterized performing field emission scanning electron microscopy transmission analyses, Vickers microhardness measurements, thermal conductivity, tensile testing. particles dispersed the tungsten boundaries within grains....
