Investigation of mechanical and technological properties of porous meshed material sheets of steel 12X18H10T
The article describes the study of porous meshed material mechanical characteristics using a structural approach, which involves determining the mechanical properties on the basis of the mesh geometric parameters (standard size), mesh quantity, mutual arrangement, mechanism of plastic deformation and quality of structure-forming element consolidation. It is shown that porous meshed materials made by diffusion welding after mesh chemical treatment has the maximum interlaminar strength for a given mesh briquette design and compression. The dependences for determining strength, plasticity and anisotropy of the porous meshed material in the plane of the sheet under uniaxial and biaxial tension are obtained. It is found that increasing the formability and weldability of sheet blanks is achieved by reducing the strength anisotropy, plasticity and thermal conductivity. To reduce the anisotropy meshes with square cells should be used, their number should be increased, the angle between them should be reduced, and compression in the process of their solid-phase coupling should be increased.
