Special Issue Information

Dear Colleagues,

This Special Issue of Materials concentrates on novel technologies and new findings related to high-temperature ceramics, as well as their development and application. With the rapid development of science and technology, materials are becoming more widely applied in extreme environments, especially those of high temperature. High-temperature ceramics, as high-temperature candidates with excellent potential, are becoming increasingly widely used in the thermal protection systems of hypersonic flight vehicles, the high-temperature components of engines, and the key components of nuclear fission reactors. In recent years, high-temperature ceramics have been developed rapidly. Due to the more severe service environment that high-temperature ceramics are subjected to, higher requirements are put forward for their performance. Thus, some new analytical models, as well as preparation, characterization and test methods for high-temperature ceramics have been proposed. We are delighted to invite contributions to this Special Issue on “Development and Application of  High-Temperature Ceramics”. In the collection, we hope to underline recent advances related to processing, microstructures, property characterization and optimization, and damage failure mechanism analyses for high-temperature ceramics. Consequently, research topics of interest may include, but are not limited to: processing; strengthening and toughening; property characterization; theoretical modeling; and damage failure mechanism analysis. Manuscripts in the form of full research papers, communications and review articles are all encouraged.

In this paper, we estimated the temperature-dependent critical inclusion size for microcracking under residual stress and applied stress for particulate-reinforced ultra-high-temperature ceramic matrix composites. The critical flaw size and applied stress for the stable growth of radial cracks under different temperatures were also estimated. It was found that under a lower applied stress, the critical inclusion size was sensitive to the temperature. Under higher applied stresses, the sensitivity became smaller. For ceramic materials with pre-existing microcracks, the crack resistance could be improved by increasing the service stress when the service stress was low. As the temperature increased, the critical flaw size of the materials decreased; the applied stress first increased and then decreased. Finally, a temperature-dependent fracture strength model of composites with a pre-existing critical flaw was proposed. A good agreement was obtained between the model prediction and the experimental data. In this work, we show a method for the characterization of the effects of temperature on the fracture behavior of ceramic-based composites. Full article

Recent years have witnessed a growing research interest in graphene-reinforced alumina matrix composites (Al2O3-G). In this paper, to better achieve the dispersion of graphene in composites, a ball milling method for adding raw materials step by step, called stepwise feeding ball milling, was proposed. The Al2O3-1.0 wt % graphene composites were prepared by this stepwise feeding ball milling and hot pressing. Then, the effects of sintering temperature and sintering pressure on the microstructure and mechanical properties of composites were studied. Results showed that the bending strength, fracture toughness and Vickers hardness of composites increased firstly and then decreased with increasing sintering temperature. The mechanical properties of composites were all at their maximum with the sintering temperature of 1550 °C. For example, the bending strength of composites reached 754.20 MPa, which was much bigger than 478.03 MPa at 1500 °C and 364.01 MPa at 1600 °C. Analysis suggested that the strength of composites was mainly related to the grain size, microflaw size and porosity. Full article
