Abstract

A 3D finite element simulation of the behavior of a prismatic sample of a magnesium-aluminum composite material AMg6-AD1-MA2-1 with an elliptical defect in the AD1 layer under axial tension was carried out, its strength and the change in the stress-strain state were determined when the thickness of the AD1 layer varied from 5 to 1, 25 mm. A change in the stress-strain state and strength during perforation transfer to the MA2-1 layer was revealed.

Abstract

It is shown that in FeAl/Fe3Al/Fe(Al) coatings, formed on a steel substrate using explosion welding and subsequent heat treatment, the main failure mechanism is cohesive failure. Peeling and spalling of coatings occur only at high loads. It has been established that the hardness of a layered FeAl/Fe3Al/Fe(Al) coating with a thickness of 440 μm increases from the substrate to the surface, reaches a maximum at a distance of 200 μm from the surface, and then decreases due to an increase in porosity. Relative wear resistance of the coating is about 1.5 times higher than that of the steel St3 substrate. [ABSTRACT FROM AUTHOR]
