“…To study kinetics of macrolocalization pattern development, presentation of positions X of local elongation centers ε xx in a sample was used as a function of total deformation time. Authors of [17] demonstrate that this approach allows determining the velocity of deformation centers movement V = dX/dt using kinetic diagrams (Fig. 3).…”

“…Process of material degradation starts with the localization of plastic deformation near structural heterogeneity and stress raisers [17] in the area of bonding of two dissimilar metals. At early stages of plastic deformation when total deformation is ε = 0.24, micro stress raisers are formed in the area of material bonding.…”

Plastic flow localization patterns in bimetal laminates at the macroscale level have been researched. It has been found that plastic deformation proceeds during the whole process of deformation and localized in base, transition and cladding layer of bimetal. Kinetics of proliferation of plastic deformation localization fronts has been traced at different stages of the curve demonstrating plastic flow in A 283 Grade +301 AISI bimetal composed of 301 AISI austenitic stainless steel and A 283 Grade low-carbon steel. Staging of deformation curves has been analyzed.

“…In this respect, particular attention is paid to composites made by combining two or more dissimilar metals into a monolithic composition that preserves the reliable linking between the constituents during further processing under operating conditions 2 . There are currently numerous methods to obtain bimetals with various functions and compositions 3 , which allow one to take into account the specificities of each type of materials. Many studies have been devoted so far to the mechanical properties of bimetals 4 .…”

The paper studies the patterns of localization of plastic deformation of a corrosion-resistant bimetal under uniaxial tension via speckle photography method. It was found that at different stages of work hardening, the distributions of local elongations have a spatio-temporal order in the form of macroscopic deformation zones. The parameters of localized plasticity in the layers of the base (ASTM A414 grade A) and cladding (AISI 304) metal are determined. The process of deformation accumulation in the fracture site of the composite is analyzed.

“…Chromium has been widely used in metallurgy, refractory and chemical industries because of its hard quality, wear resistance, high temperature resistance and corrosion resistance. Many scholars have prepared metallurgically bonded metal surface composites on the surface of steel by means of chromization [4,5]. While maintaining the excellent properties of low-carbon steel such as high toughness, weldability and impact resistance, the corrosion resistance and wear resistance of the material are improved.…”

Cr/low-carbon steel surface composites were prepared by aqueous solution co-deposition and high-temperature solid-state diffusion technology, and the macro rule of the solid-state diffusion of chromium on the surface of low-carbon steel was analyzed. The molecular dynamics (MD) method was used to simulate and calculate the diffusion process of the Cr/Fe interface, and the macro and micro diffusion mechanisms were analyzed. The results show that the diffusion of the chromium in iron is the combined action of the temperature, crystal structure and lattice distortion, and the diffusion coefficients of chromium in α-Fe and γ-Fe have little difference. The vacancy diffusion mechanism of the first adjacent transition is the main diffusion mode. In practice, chromium atoms diffuse along the grain boundaries of the low-carbon steel matrix and provide pinning at the grain boundaries to prevent grain growth. The simulation law is in good agreement with the experimental law. The variation law of the average diffusion coefficient of chromium atoms with temperature is obtained. The diffusion rate of chromium in the bcc crystal structure is obviously higher than that in the fcc crystal structure. In the same crystal structure, the diffusion coefficient of chromium increases with the increase in temperature. However, in the lattice transition temperature region, the diffusion coefficient of chromium gradually decreases with the increase in temperature until the end of the transformation.
