“…A certain orientation of the α ‐Si 3 N 4 nanowires which was developed via this technique should be suggested as a preferred one, on account of the presence (or the absence) of some specific XRD peaks; that is, the α ‐Si 3 N 4 nanowires tend to be aligned along a direction parallel to the surface of the membrane. The intensity of the peaks also suggests that the presence of the α ‐Si 3 N 4 phase increases with the increase of temperature to 1300°C, which is in good agreement with a previous report . The increase in sintering temperature seemingly favors α ‐ β phase transformation.…”

“…Si 3 N 4 ceramic have been widely recognized as the ideal tool materials for cutting the high temperature cast iron and nickel-based alloys due to its outstanding thermal properties, wear resistance, and high temperature material properties [1,2,3,4]. Currently, high-performance densified Si 3 N 4 ceramics are usually sintered by hot pressing sintering [5,6], hot isostatic pressure sintering [7], pressure less sintering [8], microwave sintering [3,4], reaction sintering [9,10], and spark plasma sintering [11,12,13]. Among the mentioned methods, microwave sintering is a new technology, which has high-energy utilization rate, safety, and free pollution.…”

The n-SiC (nanometer SiC) is added to be the additive in order to improve the mechanical performance of Si3N4 ceramics. A microwave sintered the ceramics at different temperature and holding times. The results shows that the Si3N4/n-SiC ceramics (85 wt% Si3N4 + 5 wt% n-SiC + 5 wt% Al2O3 + 5 wt% Y2O3) have the best mechanical properties at 1600 °C, which is beneficial to the densification and β-Si3N4 phase formation for 10 min: the density, hardness, and fracture toughness were 97.1%, 14.44 GPa, and 7.77 MPa·m1/2, which increased by 2.8%, 7.0%, and 13.1%, respectively, when compared with the ceramics (90 wt% Si3N4 + 5 wt% Al2O3 + 5 wt% Y2O3).

“…At present, the methods for preparation of Si 3 N 4 -based ceramic material are mainly based on the traditional sintering methods such as hot pressing [14,15], hot isostatic pressing [12], air pressure [16], pressureless [17], and reaction sintering [18,19]. In addition, there are new preparation techniques such as spark plasma sintering [20,21,22] and microwave sintering [3,13].…”

Silicon nitride (Si3N4) based ceramic tools exhibit good machinability in cutting materials such as gray cast iron, ductile iron, malleable cast iron, and superalloys due to excellent high-temperature mechanical properties. In this paper, high-performance Si3N4-based ceramic tools containing tungsten carbide (WC) and cobalt (Co) were studied. Effects of the WC content and Co content on mechanical properties and a microstructure of Si3N4-based ceramic materials were analyzed. Results showed that Si3N4-based ceramic material containing 10 wt % WC and 1 wt % Co had the best comprehensive mechanical properties at a sintering temperature of 1650 °C and holding time of 6 min, achieving Vickers hardness, fracture toughness, and room temperature bending strength of 16.96 GPa, 7.26 MPa·m1/2, and 1132 MPa, respectively. The microstructure of Si3N4-based ceramic tool material is uniform without obvious abnormal growth. The Si3N4-based ceramic tool was mainly composed of α-Si3N4, β-Si3N4, and WC phases.
