چکیده
In this study, the influence of up to 15 vol% WC or Mo2C addition Ni bonded NbC matrix cermets, prepared by pressureless liquid phase sintering in vacuum for 90 min at 1390 °C was assessed. The constituent phases and W/Mo dissolution binder were simulated thermodynamic modelling. Microstructure analysis using XRD SEM indicated that modified based cermets composed a (Nb,W)C (Nb,Mo)C solid solution cubic dispersed alloy binder. Residual present with ?10 addition, whereas completely dissolved into cermets. evolution WC/Mo2C content on formation is discussed fracture toughness, Vickers hardness transverse rupture strength

Properties of Ni/ysz Cermets Depending on Their Microstructure
A cermet (ceramic metal composite) of Nickel and Yttria stabilized Zirconia (YSZ) is the most commonly used fuel electrode for Solid Oxide Fuel Cells (SOFC). The properties of such cermets depend strongly on their microstructure. Several Ni/YSZ cermet samples with different Ni content and Ni and 8YSZ grain size have been prepared. The thermal expansion coefficient (TEC) of these samples was mea...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولEffect of SiC Nanowhisker on the Microstructure and Mechanical Properties of WC-Ni Cemented Carbide Prepared by Spark Plasma Sintering
Ultrafine tungsten carbide-nickel (WC-Ni) cemented carbides with varied fractions of silicon carbide (SiC) nanowhisker (0-3.75 wt.%) were fabricated by spark plasma sintering at 1350°C under a uniaxial pressure of 50 MPa with the assistance of vanadium carbide (VC) and tantalum carbide (TaC) as WC grain growth inhibitors. The effects of SiC nanowhisker on the microstructure and mechanical prope...
متن کاملEvaluation of Microstructure and Mechanical Properties of Ti6A14V / (WC-Co) Friction Welds
The metallurgical and mechanical properties of Ti6Al4V/(WC-Co) friction welds have ben investigated. The microstructure close to the bondline comprised a mixture of acicular and equiaxed α plus β phases. The diffusion of elements in the welded specimens has been detected. The fracture strengths of Ti6Al4V/(WC-Co) friction welds markedly improved when the cobalt content in the (WC-Co) carbide su...
