Summary: The formation of dislocations and dislocation tangles in the Al-Li alloy after pre-stretching deformation affects the precipitation behavior of different phases during aging. These defects provide nucleation sites and improve the mechanical properties and corrosion resistance of the alloy. Pre-aging treatment enhances the precipitation of a specific phase and further improves the strength and IGC resistance of the alloy.

Summary: In this study, Mo is used to generate strengthening phases and expand the region of a face-centered cubic (FCC) solid-solution phase at lower temperatures in the equiatomic VCoNi alloy. The substitution of Mo successfully adds a homogeneous L12 phase to provide strengthening effects and overcomes the limitations of the VCoNi alloy, but appropriate heat treatment is required to prevent brittleness.

Summary: A356 cast aluminum alloy with high Si content and different casting conditions has been strengthened by controlling the eutectic morphology and precipitates of intermetallic compounds. Understanding the solubility of Si-related precipitates and clusters in the α-matrix is crucial for enhancing the strength and fatigue resistance of A356 alloys. Aging heat-treatment temperature promotes the formation of these precipitates and clusters, leading to improved mechanical properties in the 110A sample compared to 130A. Ti2Si precipitation and various-sized cluster formations were observed in 110A, while 130A had fewer clusters. This indicates that different aging heat-treatment temperatures affect atom behavior and ultimately affect the mechanical properties.

Summary: An equiatomic AlCrCuFeNi high entropy alloy (HEA) was synthesized and its elemental distribution, microstructural evolution, and solidification behavior were systematically investigated through different heat-treatment schedules and characterization techniques. The results indicate that the alloy exhibits a two-phase structure of BCC and FCC phases, with the primary dendritic structure in the as-cast material. Heat treatment at 1300 degrees C resulted in the formation of Fe-Cr rich BCC phase in the dendritic region, while Al-Ni rich B2 phase and Cu rich phase were found in the interdendritic space. The role of element Cu in affecting the solidification behavior of the alloy in the temperature range of 900-1100 degrees C was highlighted. This work emphasizes the importance of understanding the microstructure evolution and solidification behavior in HEAs for their potential applications.

Summary: Heat treatment is a useful method to alter the microstructure and mechanical properties of TiAl alloys. This study investigates the effects of a heat treatment on the Ti-45Al-2Nb-2Cr-(0.2, 0.5)C alloys. The results show that the heat treatment causes lattice shrinkage of the gamma phase and changes the microstructure from nearly lamellar to duplex structure. There is an increase in fracture strain but a decrease in yield/ultimate strength for the heat-treated samples compared to the as-cast samples.

Summary: It is well known that increasing Cu levels in the third generation of Al-Li alloys can cancel weight reduction gains and reduce ductility. However, this study demonstrates that higher strength and ductility can be achieved by replacing traditional aging methods with creep aging without changing the chemical compositions. By combining hot extrusion, creep aging, and pre-strain, the precipitation kinetics of AA2060 alloy are enhanced compared to traditional aging. Contrary to traditional knowledge, a higher extrusion ratio and aging temperature can result in higher peak aging strength, with an average ultimate tensile strength of 659 MPa.

Summary: A nano-precipitate of Si-Mg2Si core-shell structure is discovered in Al alloys for the first time. The orientation relationship between the ss-Mg2Si shell and the Si core is predicted by a near row matching model based on interfacial good matching. First-principles calculation reveals that heterogeneous nucleation of Mg2Si on Si is favored due to reduction of nucleation barrier.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
