Summary: By establishing quantitative correlations among compositions, elastic constants, GFA, and mechanical properties of metallic glasses (MGs), it is possible to predict their performance in advance. Experimental data confirms the validity of this predictive approach. A strategy for designing MGs with optimal combinations of strength, toughness, and GFA is proposed to allow for high-throughput discovery of glass formers with excellent mechanical properties.

Summary: This study employed machine learning models to predict the plastic properties in CuZr metallic glasses. Molecular dynamics simulations were conducted for 100 different samples, and statistical analysis was performed on 17 materials properties. Strong correlations were found between stoichiometry, temperature, structural, and elastic properties with plastic properties. Three regression models were used for prediction, and linear and Ridge regressions showed better performance with coefficients of determination above 80% for three plastic properties. Lasso regression had lower performance with coefficients of determination above 60% for two plastic properties. Overall, this work demonstrates that molecular dynamics simulations combined with machine learning models can provide a framework for predicting the plastic behavior of complex materials.

Summary: The relationship between microstructure and mechanical property of three Zr-based bulk metallic glasses (BMGs) was investigated. The results show that the content of CuZr2-type phase increases but that of Zr6Al2Ni-type phase decreases with increasing Zr content. The plastic flow stress and strain decrease while the plasticity increases with increasing fraction of CuZr2-type cluster, which is named as geometrically unfavorable motifs (GUMs). The fitting parameters from cumulative probability statistics provide valuable clues for investigating the plastic flow and plasticity of the BMGs.

Summary: Shear transformation zones (STZs) are crucial for explaining plastic flow in metallic glasses, but their morphological and dynamical characteristics are not fully understood. Through simulations, it has been found that STZ activation occurs from the early stage of elastic deformation to the final shearing stage. STZs in the elastic and plastic ranges share similar characteristics but differ in magnitude and dynamics.

Summary: In this study, a hidden and universal relaxation mode (termed alpha' relaxation) was discovered in metallic glasses, which appears between alpha relaxation and relaxation. The excitation of the alpha' relaxation mode is found to be controlled by the energy state and the local potential energy topology. It was also observed that the activation energy and nonmonotonic behavior of alpha' relaxation reveal its intrinsic connection with alpha relaxation and relaxation. Furthermore, it was shown that the excitation of the alpha' relaxation mode can notably improve the homogeneous tensile deformability of metallic glasses.

Summary: Molecular dynamics simulations are used to investigate the mechanical properties of nanoporous CuxZr1-x metallic glasses. The study reveals a strong correlation between Young's modulus, Ultimate Tensile Strength (UTS), and porosity/composition. Increasing porosity leads to a change in nanoporous topology and a transition from brittle to ductile deformation and failure mechanisms. Genetic Programming (GP) is employed to establish scaling laws for E and UTS as a function of porosity and composition, accurately predicting their values in the entire range considered.

Summary: A family of novel Os-Co-Ta-B high-temperature bulk metallic glasses (HTBMGs) with high glass transition temperature, Vickers microhardness, and compressive strength was fabricated by introducing high-modulus refractory metal Os and strong-covalent metalloid B. The impressive strength is attributed to the strong bond characteristics especially for Ta-Os and B-B bonds. The castable OsCo-based HTBMGs with superior mechanical properties and high thermal stabilities are significant for high-temperature applications as advanced structural materials.

Summary: In this study, shafted microgears were manufactured using a microforming process. A grain-based modeling approach was used to simulate the forming process and investigate the effects of grain size on forming behavior and process performance. Five deformation zones with different hardness and stress-strain distributions were identified in the microstructures. The undesirable geometries of microgears, such as material unfilling, burr, and inclination, were observed and the inclination size increased with grain size. By redesigning the punch and adding a die insert, the forming quality of the microgears was improved.

Summary: In this study, 47 full-length HbTPS genes were identified in the Hevea brasiliensis genome, and they were divided into five subfamilies based on phylogenetic analysis. HbTPSs were found to participate in cellular components, molecular functions, and biological processes, as well as seven secondary metabolite pathways. They may be regulated by phytohormones, as suggested by the presence of cis-acting elements. RNA-Seq analysis revealed tissue-specific expression patterns of different HbTPSs. These findings contribute to understanding the role and molecular mechanism of HbTPSs and the regulation of terpenoid biosynthesis in H.brasiliensis.

Summary: Laser shock peening (LSP) treatment significantly affects the phase structure and properties of titanium-based BMG materials, promoting rejuvenation and introducing heterogeneity. This leads to improved plasticity and resistance to crack propagation. LSP-1 specimen exhibits higher hardness and plasticity, reducing fatigue peeling wear caused by brittleness. However, excessive LSP results in increased susceptibility to pitting and significantly reduces tribocorrosion resistance.

Summary: The amount of globally recycled e-waste is less than 20% of the total produced. One of the causes for this low recycling rate is the complex and expensive selective sorting of metals. However, recent research has shown that high entropy alloys (HEAs) can be made from complex alloy mixtures, reducing the dependence on pure critical metals. It has been demonstrated that e-waste can be used to produce competitive HEAs.

Summary: In this study, a novel medium-entropy alloy (MEA) (Fe65Ni15Cr10Co10)92Ti5Al3 with a dual heterogeneous structure was developed by adding Ti and Al to a previously reported Fe65Ni15Co10Cr10 MEA. The MEA exhibited ultra-high ultimate tensile strength and work hardening extent at room temperature. The addition of Ti and Al induced precipitation and resulted in a continuous FCC -> BCC martensitic transformation and a transformation-induced plasticity effect. The excellent mechanical properties of the alloy were attributed to the synergistic effects of hetero-deformation induced strengthening, precipitation strengthening, and TRIP.

Summary: This study focuses on the influence of the thermomechanical protocol on the aging or rejuvenation of glass by decoupling the thermal and mechanical processes. The results show that Labased metallic glass exhibits material hypomnesia, with a clearer rejuvenation trend observed after imposing increasing amplitude strain oscillations. There is a threshold value of the oscillation amplitude that separates the effects of the protocol into acceleration of aging or rejuvenation. This study reveals the correlation between the thermomechanical properties of metallic glass and the previous application of strain oscillations of various amplitudes, providing an effective tool for regulating the structural state of metallic glasses through a simple-operated method.

Summary: We report the formation of large and highly twinned dendrites of the Al13Fe4 approximant phase embedded in an fcc Al-rich matrix. Using a rapid cooling technique, the approximant appears as a 10-fold dendrite. The grain distributions within the arm are complex and a single dendrite arm can contain up to four different orientations. Three types of twins, namely {100}, {001} and {201} twins, have been identified. A growth mechanism involving heteroepitaxial growth from a decagonal Al-Fe quasicrystalline seed is proposed to explain the formation of these specific 10-fold motifs.
