The addition of the antidote lattice changes the hysteresis loop of the film.

Combining first-principles calculations with experimental results, it is demonstrated that the middle layer of multi-layered aluminum sheets serves as an effective barrier, preventing the diffusion of Si into the core layer. This significantly enhances both the mechanical strength and corrosion resistance of the material.

Fe additions (1.0–8.0 wt.%) to additively manufactured Ti4Al3V alloy induce a columnar-to-equiaxed grain transition, with grain boundary strengthening prevailing in yield strength enhancement at 1.5–3.0 wt.% Fe.

1. Comparative studies of the formation patterns of micro-arc coatings on the surface of titanium VT1-0, Ti-40 wt. % Nb and magnesium Mg-0.8 wt. % Ca alloys were carried out. 2. TiO2, Nb2O5, and MgO oxides have different electrophysical properties, which affects the micro-arc oxidation process and properties of the coatings formed on the metal substrates.

In case of non-uniform distribution of components in membrane alloys, the operating parameters must satisfy Sieverts' law. Fulfilment of the condition H/M < 0.2 is not sufficient to prevent hydrogen embrittlement.

The new Fe-32Ni-2.7(Ti, V, C) Invar alloy demonstrates high strength after hot forging and thermal treatment while maintaining acceptable ductility and a low coefficient of thermal expansion.

Using the MD/MC Metropolis scheme, the most probable fracture-surface structures (FS) formed on the cleavage plane were studied in simulations of the Al–Mg and Al–Ni alloys containing symmetric Σ5 boundaries with superstructures of segregations. The resulting FS structures were analyzed depending on the type of grain boundaries and the type of impurity atoms.

The article investigates and substantiates the feasibility of using acoustic emission (AE) for monitoring and diagnosing laser processing of ultra-hard materials. Using laser probing as an example, it is demonstrated that AE parameters carry valuable information about process efficiency, material properties, and underlying physical phenomena.

A key finding is the formation of a stable, partially recrystallized, bimodal microstructure in the UFG+CR state after HDEP, which is attributed to the competition between high stored energy and Zener pinning from nanoscale Al3(Sc,Zr) dispersoids

The microstructure of the Ni-Cr-Al alloy produced by a dual-wire electron-beam additive manufacturing with NiCr and Al wires has been investigated using transmission electron microscopy. It has been shown that brittle fracture and low ductility of the alloy at room temperature is associated with brittle failure of interfaces “dendrite/interdendrite” and intermetallic B2-NiAl, L10-NiAl phases.

The paper provides an insight into the grain refinement process in a model Al-Cu alloy during high-temperature severe plastic deformation, decoupled from the effects of transition metal dispersoids. It establishes that continuous dynamic recrystallization, driven by the formation and strain accumulation in permanent microshear bands, is the dominant grain refinement mechanism.

The evolution of the structure during ultrasonic welding of metals depends on the knurl height on the surface of the welding tool. Increasing the height of the teeth leads to the formation of areas of mechanical adhesion between the metals in the joint zone, increasing the proportion of fine grains in this zone but does not affect their size.
