Summary: By introducing carbides into the TiNbTaZrHf based composite, it exhibits ultra-high yield strength at room temperature and maintains high strength at high temperatures. However, the strength decreases significantly as the temperature rises, mainly due to the weakening of load-bearing effect and interfacial debonding between the matrix and carbides.

Summary: This study focuses on the Al0.8CrFe2Ni2 high entropy alloy fabricated using laser powder bed fusion with pre-alloyed powder. Heat treatment of the as-built material resulted in a dual-phase microstructure composed of face-centered-cubic grains and Al-, Ni-rich body-centered-cubic B2 precipitates. The effects of heat treatment on the alloy's properties were explored through microstructure characterization, mechanical, and corrosion testing. The results demonstrate that mechanical properties can be tailored by controlling the size of precipitates through heat treatment. Refining the precipitates improves strength without significant loss of ductility. Corrosion tests show that the as-built samples display better overall corrosion resistance compared to heat-treated samples, attributed to the influence of precipitates on micro-galvanic cell formation.

Summary: Ti particles (5 wt%) reinforced AZ91 Mg matrix composites (TiP/AZ91 composites) were prepared by powder metallurgy, resulting in improved strength and ductility compared with AZ91 alloy. The UTS significantly increased from 163 MPa to 221 MPa, and the elongation increased from 3.5% to 10.9%. The YS and hardness decreased due to slightly coarser grain size. The microstructural analysis showed uniform dispersion of Ti particles in the Mg matrix, with reduced Mg17Al12 content and formation of an Al3Ti layer at the edge of Ti particles. EBSD analysis revealed the presence of tensile twins and dislocations during tensile deformation, which contributed to the improved elongation of TiP/AZ91 composites.

Summary: The precipitation phase was tailored by adding different Sn contents to the Mg-12Gd-3Y alloy, resulting in multiphase composite strengthening. The addition of Sn had different effects on the microstructure and mechanical properties. Adding 1.0 wt% Sn produced uniformly distributed Mg5RE, Sn3RE5, and β' precipitates, while adding up to 1.5 wt% Sn increased and aggregated the Mg5RE and Sn3RE5 precipitates. The Mg-12Gd-3Y-1.0Sn alloy exhibited excellent room and elevated temperature mechanical properties.

Summary: In this study, three types of WE43 plates with different heat treatments were studied. The microstructure and mechanical properties of these plates were investigated. It was found that the number of precipitates increased as a result of aging after extrusion. The coarse grains and high Schmid factor led to the highest hardness and limited plasticity in the solution-aging after extrusion plates. The T5 plates showed the highest strength due to fine grains and multiple precipitates, while the T6 plates exhibited low ductility because of grain boundary and twin boundary cracking.

Summary: During the last decade, misfit layered calcium cobaltite (Ca3Co4O9) has been explored as a potential thermoelectric material. In this study, the thermoelectric properties of Ca3Co4O9 were improved by synthesizing composites with different wt.% of Cu. The composites were consolidated into bulk ceramics and their structure was analyzed, revealing a multiphase system. The sample containing 5% Cu demonstrated the highest power factor at 973K, which resulted from the simultaneous improvement in electrical conductivity and Seebeck coefficient. The conduction mechanisms were further discussed.

Summary: A new method of ultrasonic vibration melting infiltration was investigated and applied to fabricate Ti6Al4V (TC4) lattice structure-reinforced Mg-10Gd-2Y-1Zn-xZr (VW92) alloy matrix composites. The edge-to-edge matching model indicates that the alpha-Mg grains can nucleate on the TC4 lattice structure due to the well-matching and possible orientation relationships (ORs) between alpha-Mg and alpha-Ti. Interfacial reaction occurred in the TC4/VW92 + 0.5 wt% Zr composites, and the reaction product was confirmed to be Al2Zr3, AlZr2 and alpha-Ti (Zr) particles formed by continuous solution of Zr-Ti. Among the interfacial products, the presence of the brittle AlZr2 phase hinders the load transfer, but the formation of a coherent interface between alpha-Ti (Zr) and alpha-Mg improves the interfacial bonding strength of the composites.

Summary: Ti particles addition in Mg AZ31/Al 6082 composite sheets prepared by hot rolling was investigated in this study to understand the influence on mechanical behavior and microstructure. The results revealed that Ti particles were uniformly distributed at the interface, leading to a reduction in Mg-Al intermetallic compounds during annealing treatment. After annealing, the Mg/Al-Ti sheet exhibited improved tensile strength and elongation compared to the Mg/Al sheet. Ti particles addition had minimal effect on the grain size, texture type, and tensile fracture morphology of the Mg and Al layers in the composite sheets. This study provides a new perspective on understanding Mg/Al composites through the addition of metal particles.

Summary: In this paper, a design strategy was proposed to quantitatively investigate the composition and process conditions for the preparation of ultrafine grain magnesium alloys. Five machine learning algorithms were used to analyze and make predictions based on a dataset of magnesium-manganese-based wrought alloys. The main factors affecting the formation of ultrafine grains were identified, and suggested routes for preparing ultrafine grain magnesium alloys were extracted from the tree models. Experimental validation showed that the grain sizes were close to the predictions, highlighting the effectiveness of the proposed design strategy.

Summary: In this study, In2O3/PANI composites were synthesized using the hydrothermal technique to explore their sensing capabilities for NO2 gas. The gas sensing properties, such as response/recovery time, optimal temperature, and recyclability, were investigated by analyzing the morphology, purity, and crystal structures of the samples. The In2O3/PANI-1 sensors exhibited high responses, quick response and recovery times, and a low detection limit to NO2 gas at a working temperature of 250 degrees C. The fundamental detecting mechanism for NO2 gas and the electrical characteristics of the In2O3/PANI composites were also discussed.

Summary: Mg-based hydrogen storage materials have attracted attention for their high hydrogen storage density, abundant resources, and environmental friendliness. However, challenges such as slow kinetics, high absorption/desorption temperature, and poor cycling stability hinder their large-scale use. Recent developments in alloys, nano-structure control, catalytic modification, and multiphase composites have made progress in addressing these challenges. Further improvements are needed in hydrogen storage capacity, adsorption/desorption temperature, reaction rate, and cycling life.
