High temperature flexural strength of ZrB 2 –20 vol% SiC ceramics ( ZS ) up to 1600°C in high purity argon atmosphere was significantly improved by adding 5 WC , but degraded when ZrC added. –5 ceramic ZSW has a very (mean ± SD) 675 33 MPa at 1600°C, and also an elastic transgranular fracture mode observed. According the analysis modes crack origins ceramics, improvement above 1000°C attributed removal oxide impurities from grain boundaries.
Recently, the number of published papers on sintering technologies activated by current have increased exponentially. In particular, it has been reported that application electric field as high 120 V/cm permitted instantaneous full densification yttria stabilized tetragonal zirconia at unusual low temperature 850°C. The mechanisms so called flash phenomenon are elucidated analyzing distribution bulk sample under field.
Abstract Approaching state‐of‐the‐art areal and volumetric capacitances while maintaining high‐power characteristic is a big challenge that promotes practical application of flexible solid‐state micro‐supercapacitors (MSCs), which have recently attracted great attention with the rapid development microelectronics. Herein, it reported freestanding extrahigh conductive Ti 3 C 2 T x (MXene) films excellent flexibility effectively controlled thickness ranging from 1–21 µm performed as...
Cold sintering is an innovative low-temperature processing technique which allows consolidation of several ceramics. Despite recent research activities on the cold functional and structural ceramics, analytical study accounting for grain growth phenomena still missing in literature. In this work, we provide a theoretical analysis mechanisms active during sintering. The considers two approaches, characterised by application either isostatic or uniaxial pressure. Physical microstructural...
Abstract Guided by the theoretical prediction, a new MAX phase V 2 SnC was synthesized experimentally for first time reaction of V, Sn, and C mixtures at 1000 °C. The chemical composition crystal structure this compound were identified cross-check combination first-principles calculations, X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), high resolution scanning transmission electron microscopy (HR-STEM). stacking sequence Sn layers results in space group P6 3 /mmc. - c...
Abstract The ternary or quaternary layered compounds called MAB phases are frequently mentioned recently together with the well-known MAX phases. However, generally referred to transition metal borides, while carbides and nitrides different types of crystal structure although they share common nano-laminated characteristics. In order prove that can same type extend composition window from two new phase Zr 2 SeB Hf Cr AlC-type (211 phase) were discovered by a combination first-principles...
In this work, a bulk Nb 4 AlC 3 ceramic was prepared by an in situ reaction/hot pressing method using Nb, Al, and C as the starting materials. The reaction path, microstructure, physical, mechanical properties of were systematically investigated. thermal expansion coefficient determined 7.2 × 10 −6 K −1 temperature range 200°–1100°C. conductivity increased from 13.5 W·(m·K) at room to 21.2 1227°C, electrical decreased 3.35 6 1.13 Ω ·m 5–300 K. possessed low hardness 2.6 GPa, high flexural...
Highly transparent pure alumina with an average grain size of 200 nm was fabricated by means high‐pressure spark plasma sintering. The sintered either at 950° or 1000°C for 10 min under applied pressure 500 MPa had in‐line transmission about 64% a wavelength 645 nm. application high allowed to obtain highly full dense low temperatures no considerable growth.
Textured Nb 4 AlC 3 ceramic was successfully fabricated in a strong magnetic field followed by spark plasma sintering. The optimized suspension parameters for slip casting were determined to be 20 vol% and 2 wt% polyethyleneimine dispersant of powder deionized water. After texturing 12 T cold isostatic pressing, the relative green densities 50.4% 58.7%, respectively. A dense sample obtained sintering at 1450°C under pressure 30 MPa vacuum. X‐ray diffraction analysis revealed that preferred...
