“…Certain of the popular kinds of corrosion for "Al" which are autonomous of the corrosive condition contain "pitting", "stress-corrosion cracking", "exfoliation", "intergranular", and "galvanic" [57] . The non-heat manageable alloys have the larger corrosion persistence against common corrosion compared to the heat manageable alloys.…”

Aluminum–Gallium doped with titanium by using ONIOM method through structural, electrical, and thermodynamic properties was studied in detail. Crystal structure of Ti–(Al–Ga) surface was coated by S- & N-heterocyclic carbenes of benzotriazole (BTA), 2-mercaptobenzothiazole (2MBT), 8-hydroxyquinoline (8HQ) and 3-amino-1,2,4-triazole-5-thiol (ATR). The “NMR” spectroscopy of the adsorption of BTA, 2MBT, 8HQ, and ATR on the Ti–doped Al–Ga nanoalloy surface represents that this surface can be employed as the magnetic S- & N-heterocyclic carbene sensors. In fact, “Ti” site in “Ti–(Al–Ga)” nanoalloy surface has bigger interaction energy amount from “Van der Waals’ forces” with BTA, 2MBT, 8HQ, and ATR that might cause them large stable towards coating data on the nanosurface. It has been estimated that the criterion for choosing the surface linkage of “S” and “N” atom in BTA, 2MBT, 8HQ, and ATR in adsorption sites can be impacted by the existence of close atoms of aluminum and gallium in the “Ti–(Al–Ga)” surface. The fluctuation of “NQR” has estimated the inhibiting role of BTA, 2MBT, 8HQ, and ATR for Ti–doped Al–Ga alloy nanosheet due to “S” and “N” atoms in the benzene cycle of heterocyclic carbenes being near the monolayer surface of ternary “Ti–(Al–Ga)” nanoalloy. Moreover, “IR” spectroscopy has exhibited that Ti–doped Al–Ga alloy nanosheet with the fluctuation in the frequency of intra–atomic interaction leads us to the most considerable influence in the vicinage elements generated due to inter–atomic interaction. Comparison to amounts versus dipole moment has illustrated a proper accord among measured parameters based on the rightness of the chosen isotherm for the adsorption steps of the formation of BTA @Ti–(Al–Ga), 2MBT @Ti–(Al–Ga), 8HQ @Ti–(Al–Ga), and ATR @Ti–(Al–Ga) complexes. Thus, the interval between sulfur, nitrogen and oxygen atoms in BTA, 2MBT, 8HQ, and ATR during interaction with transition metal of “Ti” in “Ti–(Al–Ga)” nanoalloy, (N→Ti, O→Ti, S→Ti), has been estimated with relation coefficient of R² = 0.9509. Thus, the present has exhibit the influence of “Ti” doped on the “Al–Ga” surface for adsorption of S- & N-heterocyclic carbenes of BTA, 2MBT, 8HQ, and ATR by using theoretical methods. Furthermore, the “partial electron density” or “PDOS” has estimated a certain charge assembly between Ti–(Al–Ga) and S– & N–heterocycles of BTA, 2MBT, 8HQ, and ATR which can remark that the complex dominant of metallic features and an exact degree of covalent traits can describe the augmenting of the sensitivity of “Ti–(Al–Ga)” surface as a potent sensor for adsorption of BTA, 2MBT, 8HQ, and ATR heterocycles.

The study aims to investigate the influence of fraction of coarse undeformed particles on the microstructure evolution and mechanical properties of alloys processed by isothermal multidirectional forging (MDF). For this purpose, Al-Mg-Ni-Sc-Zr-based alloys with different Ni concentrations and a fraction of Al3Ni particles of solidification origin phase were subjected to MDF at 350 °C. Precipitates of the L12-structured Al3(Sc,Zr) phase retained their structure, morphology, and size after MDF and were coherent with the aluminum matrix. The Al3Ni phase particles stimulated the nucleation of recrystallized grains and contributed significantly to the formation of an ultrafine-grained structure. The uniformity of the grain structure increased, and the average grain size decreased with an increase in the fraction of Al3Ni particles. A fine-grained structure with a mean grain size of 2.4–3.4 µm was observed after MDF with a cumulative strain of 12. The results demonstrate that a bimodal particles size distribution with a volume fraction of nanoscale f~0.1% and microscale f~8% particles provided for the formation of a homogenous fine-grained structure after MDF and improved the mechanical properties.

“…The process of the chemical modification of hypoeutectic silumins was described in 1921 [41]. Since then, a lot of works have been written showing the influence of various elements, chemical compounds [42][43][44][45] and the technological processes [46][47][48][49][50][51][52][53][54][55][56][57] on the microstructure and mechanical properties of the tested silumins. Unfortunately, despite such a significant amount of research, it has not been possible to clearly identify the mechanisms causing microstructure refinement and increases in mechanical properties.…”

Unmodified hypoeutectic silumins have a microstructure composed of large-sized phases, which are the reason for their low mechanical properties. Many years of research have shown the modifying effects of many chemical elements and their compounds, including the master alloy consisting of Al-Ti-B, often in the form of the finished AlTi5B alloy. In this work, it was decided to check how the proportions of Ti and B content in the Al or AlSi-based master alloy affect the microstructure and mechanical properties of a hypoeutectic silumin, AlSi7Mg. It has been shown that a master alloy containing silicon (with the participation of Al + Ti + B) has a more effective impact on the refinement of the microstructure, and thus an increase in the mechanical properties of the AlSi7Mg alloy, than a master alloy without silicon. It has been shown that the ratio of titanium to boron content in the very-often-used AlTi5B modifier is not always optimal. It has been shown that the use of a master alloy with a composition similar to that of modified silumin with titanium and boron in a 2:1 ratio allows the obtaining of an AlSi7Mg alloy with higher mechanical properties than the alloy after the modification of the AlTi5 master alloy.
