Abstract
Quenching has been widely used as a strengthening strategy in metals and glass; however, it is rarely applied to ceramics due to the thermal shock effect. In this work, several types of ceramic rods including commercial corundum, Al2O3, ZrO2, TiB2, and B4C were quenched in silicon oil for investigation. The flexural strength of all these ceramic rods showed an increase of 5.1%‒23.6% after quenched at 500°C. The strengthening mechanism was likely related to the transient stress at initial quenching stage. This work demonstrates that the quenching treatment is a potential method to strengthen ceramics.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
