Summary: Zirconia ceramics with superior mechanical properties were fabricated by adding SiC whiskers and SiC particles and using oscillatory pressure sintering technique. The ceramics exhibited improved Vickers hardness, bending strength, and fracture toughness. The enhanced toughness was attributed to synergistic toughening effects including whisker toughening, stress-induced phase transformation toughening, and particle dispersion toughening.

Summary: Measuring the thermal shock crack growth process is crucial for understanding the failure mechanisms and reliability of ceramic materials and structures. In this study, a self-made water quenching system was used to conduct thermal shock tests on alumina and zirconia ceramics. The thermal shock process was recorded using high-speed digital image correlation (DIC). By analyzing the speckle image change on the sample's surface, the process of thermal shock crack initiation and propagation in the two ceramics was determined. It was found that alumina exhibited a faster crack growth rate compared to zirconia, which was attributed to different material parameters. This paper presents an in-situ measurement method that can help identify and predict thermal shock damage in ceramic components.

Summary: ZrO2 fiber toughened and non-fiber toughened Al2O3/ZrO2(Y2O3) directionally solidified eutectic ceramics (DSECs) were prepared and their microstructures and mechanical properties were investigated. Both types of DSECs had similar colony structures composed of α-Al2O3, c-ZrO2, and m-ZrO2. The phase spacing decreased with the growth rate and the fiber toughened DSECs showed higher fracture toughness compared to non-fiber toughened DSECs due to crack deflection, bifurcation, and fiber debonding mechanisms.

Summary: The study found that both the Y2O3 content and pulling rate have a significant impact on the tensile strength of directionally solidified eutectic Al2O3/ZrO2 ceramics. The maximum tensile strength was observed at 1% Y2O3 content and 10 mm/h pulling rate. Additionally, high m-ZrO2 phase mass fraction and high intercolony area fraction were found to be detrimental to tensile strength, while grain refinement strengthening and whisker toughening can enhance tensile strength.

Summary: In this study, the resistive switching in hafnium dioxide (HfO2) and aluminum oxide (Al2O3) bilayered stacks was investigated using in-situ transmission electron microscopy and X-ray energy dispersive spectroscopy. The change in conductance of the HfO2/Al2O3 stack during electrical stressing is attributed to the formation of extended nanoscale defects at the HfO2/Al2O3 interface and the migration and re-crystallization of Al into the oxide bulk. Two competing physical mechanisms, oxygen ion redistribution and Al species migration, were found to be involved in the switching process. The low diffusion barrier of the active Al electrode causes severe Al migration in the bilayered oxides, leading to device failure in resetting and limiting overall switching performance and material reliability.

Summary: The effect of microstructure on crack resistance and cryogenic toughening in a 3.5 wt% Ni high-strength low-alloy (HSLA) steel was investigated. The results show that lamellarization treatment significantly improves impact toughness and reduces ductile-brittle transition temperature. This improvement is attributed to the refinement of martensitic block size and the increase in high angle grain boundaries.
