“…As shown in Figure 7A, for the NiFe 2 O 4 ceramics without adding TiN, the intergranular interspaces were larger and the grains grew on a relatively small scale, where the grains relatively loosely packed and the grain boundary bonding strengths were comparatively lower. Grain size, relative density, and grain boundary bonding strength are known to be among the most significant items determining the mechanical strength of composite 18 . As a result, the porosity was so high that the bending strength was relatively low.…”

“…Grain size, relative density, and grain boundary bonding strength are known to be among the most significant items determining the mechanical strength of composite. 18 As a result, the porosity was so high that the bending strength was relatively low. With increased content of TiN nanoparticles, the micropores were sustainedly eliminated due to the gradual grain growth and close combination of grains.…”

“…The introduction of TiN nanoparticles plays a dominant role on the sintering behavior. The variation of TiN nanoparticles can significantly affect the kinetics of densification and grain growth, grain boundary motion, pore mobility, and pore removal 18 . Detailed understanding of sintering behavior is one of the key factors to tune the NiFe 2 O 4 microstructures for specific applications.…”

There is an intense desire for the substitution of the consumable carbon anode by inert anode (also called non-consumable or oxygen-evolving anode) in the Hall-Héroult process, which would drastically reduce the substantial emission of greenhouse gases such as CO 2 and perfluorocarbons. 1−3 The upgrading of suitable non-carbon anode is highly challenged on account of the numerous restrictive requirements for inert anode materials in the rugged environment of Al electrolytic cell. 2 The basic requirements for an inert anode are as follows: prominent oxidation resistance at high temperature, remarkable corrosion resistance to electrolyte molten salt, high electric conductivity, excellent thermal shock resistance, mechanical robustness, and so on. Up to now, despite major research efforts from Al producers and academic laboratories, no acceptable inert anode material has yet been found for long-term use in industrial Al electrolytic cell.Among the possible inert anode materials (namely, metal, ceramic, and cermet) that have been explored, NiFe 2 O 4based cermet is ranked as the most appropriate candidate, largely owing to the accredited combination of the features of NiFe 2 O 4 ceramics and metals, namely, excellent oxidation resistance at high temperature and high corrosion resistance

Microstructure, Mechanical Properties, and Reinforcement Mechanism of Second-Phase Reinforced TiC-Based Composites: A Review

TiC ceramics have the characteristics of high melting point and density, and titanium reserves on earth are extremely large; therefore, TiC ceramics are considered ultra-high temperature materials with great research value. However, the development of TiC-based ultra-high temperature composites has been seriously hindered by their poor mechanical properties. At present, improvement of the mechanical properties of TiC is mainly accomplished by adding a second phase. In this paper, the research status of modified elements-, nitrides-, and metal-reinforced TiC matrix composites is presented. The microstructure, phase composition, and toughening mechanism of TiC matrix composites reinforced by a second phase are described. The influence of the reaction products on the matrix during the toughening process is also discussed.
