Summary: The research revealed that the formation and evolution of GPI and GPII zones during natural aging had a significant impact on the mechanical properties of the Al-7.6Zn-2.7Mg-2.0Cu-0.1Zr-0.07Ti alloy. The Zn/Mg atomic ratio, mean radius, number density, and volume fraction of the GP zones also played crucial roles in influencing the mechanical properties of the alloy.

Summary: This study investigated the influence of processing parameters on GS Cu-Al alloys with different stacking fault energies (SFEs). Results showed that the 6 mJ/m(2) specimen processed for 15 minutes exhibited superior strength and ductility, with a significant hetero-deformation induced stress from the accumulation of geometrically necessary dislocations (GNDs). Microstructure observations revealed deformation twins in the gradient layer of the 6 mJ/m(2) specimens.

Summary: The use of lightweight alloys, such as magnesium, is crucial for improving fuel efficiency and reducing emissions in automobiles, as well as increasing the range of electric vehicles. This study investigated the effects of SiC nanoparticles on the microstructure and mechanical properties of Mg-Al-Zn-Mn alloy composites. The addition of SiC resulted in significant grain refinement, more uniform phase dispersion, and improved tensile strength, making it a promising material for strengthening light alloys.

Summary: This study proposes a novel approach of room-temperature random vibration (RRV) to suppress the challenges faced by conventional thermal strengthening treatments. The microstructures of the 2219 Al-Cu alloy were found to change after random vibration treatment, with the generation of dislocation networks and solute clusters, leading to improved mechanical properties.

Summary: This study applied cyclic deformation to an Al-Mg-Cu alloy and found that it increased the strength and ductility of the alloy by introducing dislocations and promoting cluster formation. The aging behaviors of the cyclically-strengthened (CS) samples were studied, and it was found that recovery and precipitation promotion occurred regardless of pre-aging. Pre-aged CS samples showed higher strength, but interestingly, after subsequent aging, the mechanical properties of pre-aged and non-pre-aged CS samples became the same.

Summary: Fully dense powder metallurgy (PM) Ti-4Fe-0.2O-3Cu-0.4Si alloy was produced using spark plasma sintering (SPS) and hot extrusion to develop an inexpensive high strength dual-phase Ti alloy. The addition of Si solute remarkably enhanced the microstructure stability and yield strength of the alloy at high temperature. The principal strengthening mechanisms were grain refinement and solid solution phenomena, leading to a comparatively higher tensile strength of the alloy compared to conventional Ti-6Al-4V alloy produced by a similar method.

Summary: Al-Cu-Mg-Ag single crystals with five different orientations were studied to investigate the precipitation behavior during stress aging. The formation of S precipitates increased with applied stress, and the distribution of omega 1/omega 2 varied depending on the plane orientation of single crystals. The hardness of single crystals with (6 5 10) orientation increased the most after stress aging, showing good modeling of hardness changes with applied stress and plane orientations.

Summary: The microstructure of Al-Cu-Yb and Al-Cu-Gd alloys in different states was observed and the effects of annealing on microstructure, mechanical properties, and forming properties were studied. The research revealed different recrystallization starting temperatures for the alloys within specific temperature ranges, and annealing resulted in reduced hardness and tensile properties of the alloys.

Summary: The addition of 0.5 wt% Li to an Al-Cu-Mg alloy results in significant strength increases without sacrificing ductility, mainly due to modified precipitation behavior. The strengthening sources in unstretched and stretched alloys are fundamentally different, with Li favoring a high density of GPB zones in unstretched alloys and refined S-phase precipitates in stretched alloys. These modified precipitates with Li enrichments elucidate the strengthening origin in Li-added Al-Cu-Mg alloys under various conditions.

Summary: The coarsening behavior of strengthening particles in peak-aged Al-Cu-Mg-Ag alloy during creep at 150 degrees C and 165 degrees C has been studied. It was found that the average thickness and diameter of {111}Al omega plates strongly depend on creep time and less on applied stress levels and plastic strain during creep. The volume fraction of omega particles increased during long-term creep and exceeded the value after peak aging. S-phase and theta'-phase independently nucleate and intergrow to form precipitate complexes. The size of the complex particles is sensitive to the plastic strain level achieved at different applied stresses during creep.

Summary: Surface nano-crystallization techniques have been developed to optimize materials' structure and mechanical behavior. A constitutive model incorporating grain refinement hardening is presented to simulate the technique, with precise predictability of grain size evolution during plastic deformation. This model has the potential to be a promising tool for studying the dynamic evolution of microstructures under plastic deformation.
