Summary: In this paper, a mixed constraint scheme using a global Gerchberg-Saxton algorithm is implemented for the improved generation of phase holograms from multiplane intensity distributions. The performance of the proposed method is evaluated compared to other algorithms in various scenarios involving intensity distributions of up to nine independent planes. The careful selection of parameters in the mixed constraint hologram generation technique can lead to even greater improvements in reconstruction quality, as validated by numerical results.

Summary: We propose a strategy to develop a novel bulk Al/SiC composite with a nacre/foam hybrid structure to combine the lightweight of foams with the strength and toughness of nacre. The foam is strengthened with 3D nanofiber networks, and new particle-bubble co-assembly and selective infiltration technologies are utilized. The resulting nacre/nanofiber reinforced foam composite exhibits higher specific strength and toughness than other composites and engineering materials.

Summary: This study investigates and characterizes the microstructure and damage mechanism of an aluminum-alumina interpenetrating composite to better understand its properties. The composite, consisting of a fine-pored Al2O3 preform and an AlSi10Mg cast alloy, is fabricated using gas pressure infiltration. Digital image correlation (DIC) is applied directly on the SEM images without the need for a speckle pattern, due to the contrast between the ceramic and metallic phases. The microstructure analysis and DIC results are correlated with the load level derived from stress-strain curves to gain a deeper understanding of the damage behavior in interpenetrating metal ceramic composites.

Summary: The corrosion response of the Al-Si alloy/SiC foam interpenetrating phase composite (IPC) was investigated. SiC foams with different pores per inch (PPI) index were used to fabricate the IPCs. The corrosion resistance deteriorated in all the IPCs except for 20PPIC due to the incorporation of the reinforcing phase, which resulted in the formation of a less disrupted passive film and restricted pit growth.

Summary: Interpenetrating phase composites (IPC) based on additively manufactured alumina microlattices and infiltrated epoxy are lightweight, strong, and tough, demonstrating high specific strength and energy absorption. Experimental and simulation studies show improved fracture toughness and progressive material failure contribute to the enhanced strength and lengthened stress plateau. The potential of using strong ceramic and epoxy materials for high-performance engineering applications is highlighted.

Summary: Ceramic matrix composites (CMCs) are refractory materials increasingly used in various industries. A new additive manufacturing process is being tested to produce CMCs faster and more cost-efficiently, incorporating laser melting technology. The process allows for higher component wall thicknesses and material joints.

Summary: This work presents the results of nanosecond laser-induced surface structuring of AlN ceramic. It demonstrates the change in surface morphology from ripples structure to oriented periodic microstructures under different ambient air pressures. The properties of the formed microstructures are studied in detail, and the minimum laser pulse number and energy density threshold for their formation are identified.

Summary: This study demonstrates the controlled incorporation of carbon nanotubes (CNT) with alumina and zirconia nanoparticles using an electrostatic nano-assembly method, resulting in the fabrication of homogeneous composite granules. The spark-plasma-sintered composite granules exhibited significantly higher electrical conductivity compared to a homogeneous composite artifact. This novel fabrication method using electrostatic integrated assembly shows potential for the development of multiscale and multicomponent composite materials.

Summary: The thermal and elastic behavior of an interpenetrating metal ceramic composite (IMCC) consisting of ceramic foam and a lightweight aluminum alloy was investigated at elevated temperatures. The study found that the IMCC exhibited hysteresis behavior, which could be explained by internal stress relaxation, reduction of micro voids, and interfacial detachment.

Summary: A novel Fe2O3-CaSiO3 (FCS) composite microwave dielectric ceramic was synthesized through solid-state reaction method. The relationship between the phase composition, microstructure, relative density of the composite ceramics and their microwave dielectric properties was investigated. The phase compositions of the prepared samples were CaSiO3 and Fe2O3, and the Q x f values of the FCS ceramics were positively correlated with the phase content of CaSiO3. The effect of microscopic morphology on the microwave dielectric properties of the FCS ceramic samples was studied by SEM technique. EDS analysis confirmed the phase composition of the ceramic samples as Fe2O3 and CaSiO3. Finally, the FCS ceramics sintered at 1180°C for 4 h exhibited excellent microwave dielectric properties with ε(r) = 8.69, Q x f = 28,000 GHz, τ(f) = -24.29 ppm/°C.

Summary: This paper investigates the micro-selective laser melting fabricated triply periodic minimal surface sheet lattice and epoxy interpenetrating phase composites. To enhance the specific energy absorption, an optimized lattice structure is proposed and the effects of fabrication directions on mechanical responses are presented. The results show that the modified lattice structure outperforms the original one. In addition, the interpenetrating phase composites exhibit a significant improvement in specific energy absorption. The simulation results reveal the interaction effects between the lattice and epoxy in the composites.
