Summary: This paper discusses the effect of deep cryogenic treatment (DCT) on the evolution of natural and artificial aging of Al-Mg-Si alloy EN AW 6026. The study provides evidence of DCT effect on dispersoids and their development in aluminum alloys. DCT induces reformation and regrowth of dispersoids during natural aging, leading to changes in shape and chemical composition. It also affects the hardness evolution with aging time. The study also explores the influence of DCT exposure duration and homogenization temperature on the hardness evolution during natural aging.

Summary: This study developed novel Al clad Mg composites through continuous extrusion method, showing good metallurgical bonding between the Al shell and Mg core even without preheating of the Mg alloy. The fine-grained microstructure contributed to a significant enhancement in ultimate flexural strength (UFS) to 452 MPa. Preheating of the Mg alloy resulted in complete dynamic recrystallization (DRX) and modified texture of the Mg alloy, leading to a significant improvement in the bendability of the Al/Mg composite.

Summary: The presence of short-range chemical order in metals can significantly affect their mechanical behavior. However, determining the distribution of chemical order in complex alloy systems is challenging. In this study, we use aberration corrected scanning transmission electron microscopy (STEM) and spatial statistics methods to identify and quantify chemical order in the BCC-TiVNbHf(Al) system. Through null hypothesis tests, we differentiate the experimental data from random chemical distribution and find that the experimental results deviate significantly from both random solid solution and fully ordered structures. We also observe and quantify the enhancement of short-range order with the addition of Al. These findings provide valuable insights into the local chemical order in TiVNbHf(Al) alloys and demonstrate the usefulness of spatial statistics in characterizing nanoscale short-range order in complex systems.

Summary: In this study, the comprehensive performance of a ternary Al-8Zn-1Mg alloy was improved through room-temperature rolling, resulting in comparable or even better tensile properties than conventional alloys with more complex compositions. The fine-grain strengthening, dislocation strengthening, and hetero-deformation induced strengthening were found to contribute to the increased yield strength of the alloy. The delicate balance between strength and elongation was attributed to the formation of profuse microbands induced by high Zn solute atoms and stress.

Summary: In this study, the effects of minor Ti, Mn, Cr, Zr, and Er additions on cast Al-Zn-Mg-Cu alloys were investigated. The addition of Ti significantly refines the ingot grains, while Mn and Cr additions reduce impurities and form specific phases. The joint addition of Ti, Mn, Cr, Zr, and Er creates a bulk composite phase. The alloy with the joint addition of these elements exhibits the highest hardness due to collaborative strengthening effects.

Summary: This study investigates the degree of high energy proton channelling in strongly textured samples and finds that specific crystal orientations can lead to higher degrees of proton channelling, affecting the energy deposition by 40%. Care must be taken when quantifying damage in textured samples using a single grain orientation, and to compensate for channelling effects, damage from ion irradiation should be quantified by averaging across multiple grain orientations.

Summary: The paper presents a classical model that predicts the interaction between amorphization and iron loss in Zircaloys, focusing on iron release and transport as the controlling factor. The model can explain the growth rate of the amorphous layer, the rate of iron loss, and how they are affected by flux, temperature, and initial SPP iron concentration. It also accounts for the observed occurrence of an amorphous layer only in an intermediate temperature range as a result of the competition between fundamental mechanisms.

Summary: Zirconium alloys used in pressurized water reactors are subjected to neutron exposure, resulting in the accumulation of defects and dislocations. Through synchrotron microbeam X-ray diffraction measurements and atomistic simulations, we observe and explain the variation of dislocation density as a function of exposure. In the high dose limit, the population of dislocation loops in dynamic equilibrium follows a power law distribution with an exponent of approximately 2.2, which compares favorably with experimentally measured values.

Summary: Discontinuous precipitation (DP) is a common mechanism for solid solution decomposition, resulting in the formation of precipitate layers and solute depleted matrix along a moving boundary. The morphology of DP regions is highly complex, and the behavior of dislocations and twins within such structures during deformation is not well understood. A 3-dimensional (3D) analysis is necessary to reveal the true morphology of DP. This study presents the first 3D investigation of DP using a novel PFIB based serial sectioning method. The AZ80 alloy studied exhibits an interconnected network of DP regions within a connected matrix, with varying widths of DP regions.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: The limited slip systems of magnesium (Mg) and its alloys hinder their wide applications. By conducting tensile straining experiments, researchers discovered a rate-dependent transition in the dislocation mechanisms of Mg alloys. At high strain rates, glissile dislocations dominate, while easy-glide dislocations dominate at low strain rates. Abundant glissile dislocations do not necessarily improve ductility.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.

Summary: A novel testing system for miniature specimens is designed to characterize the plastic response of materials for which conventional full-size specimens cannot be extracted. The system has an automated operation process, which reduces the damage to specimens caused by manual handling and improves the stability of the test results. The experiments show that the miniature specimens extracted from stainless steel and aluminum have high reproducibility, and the results are consistent with those of conventional-sized specimens. A correction procedure is provided to consider the influence of surface roughness and heat-affected zone caused by wire EDM.
