Summary: Doping of La and Co in KNbO3 ceramics leads to a phase transition from orthorhombic to cubic, reducing the optical bandgap and improving leakage while slightly weakening ferroelectric properties. Co doping decreases the bandgap, while La doping has the opposite effect. La doping optimizes defect levels and inhibits leakage.

Summary: The influence of annealing temperature in the range of 600-1200 degrees C on the mesostructure and properties of Y2O3:Yb3+ green bodies was investigated. It was found that annealing at the maximum possible temperatures without approaching particle centers is necessary for sintering. Green bodies annealed at 800 degrees C showed optimal mesostructure, resulting in the highest densification efficiency during subsequent vacuum sintering.

Summary: YAG:Sm3+ transparent ceramics with 3-15 at.% Sm3+ doping were prepared by solid-state reactive sintering. The effect of samarium ions concentration on the microstructure and optical properties of the ceramics was investigated. It was found that the solubility limit of samarium ions in the garnet matrix was within the range of 9-11 at.%. The absorption coefficients corresponding to Sm3+ ions transitions increased linearly with increasing Sm3+ doping, and the intensities of the satellites and the broadening of the main spectral lines also increased with the concentration of Sm3+ ions. Highly-doped YAG:Sm3+ ceramics with 9 at.% Sm3+ ions showed low optical losses at 808 nm and a high absorption coefficient at 1064 nm, making them suitable for suppressing parasitic oscillations in YAG:Nd3+ lasers at 1064 nm.

Summary: The experimental results reveal a non-monotonic relationship between solution heating rate, mechanical properties, microstructure, and texture of the Al-Mg-Si-Cu alloy. Increasing heating rate affects strength, work hardening, plastic strain ratio, microstructure transformation, and texture intensity in a complex manner. Both microstructure and texture evolutions are weakly affected by heating rate, indicating that improving heating rate may not always be favorable for certain material properties.

Summary: Fine equiaxed dendrites were present in the fusion zone of Incoloy alloy 800 plates joined by laser welding, with an hourglass shaped fusion zone that was slightly larger on the top surface. Mechanical testing showed that joints failed in the weld zone at lower scanning speeds due to the presence of Laves phases, with ductile fracture demonstrated at higher scanning speeds and brittle fracture at lower scanning speeds.

Summary: Flash-sintered ceramics show better mechanical deformability than conventional sintered ceramics, and the high-density defects formed under electrical field plays a key role. However, direct experimental evidence for defect formation and evolution is lacking. In this study, in situ TEM experiments were conducted to observe the defect dynamics in flash-sintered and conventionally sintered TiO2. The results showed that both types of samples exhibited the coalescence of point defects and the formation of stacking faults under electrical field. Surprisingly, the fault growth rate in flash-sintered samples was 10 times higher than that in conventionally sintered samples, and the formation of the Magneli phase was only observed in flash-sintered samples.
