Study of anisotropy in the properties of material prepared of powdered iron

We have used mathematical modeling with experimental verification of the results to study anisotropy in the properties of materials prepared of powdered iron. In fabrication of the powdered material, anisotropy arises in the structure as a result of the characteristic features of the technology, which affects the options for using the material. We have experimentally studied the degree of anisotropy in materials fabricated from powdered iron with different pressing forces. We propose mathematical models for the macrostructure of the powdered material, and test their adequacy to experimental data. We conclude that the degree of anisotropy in the powder material increases as it is compacted by increased pressing force. The structure of the material at the mesoscopic level after sintering can be considered as transverse isotropic, while the properties (depending on the degree of compaction of the material) can be described by a hexagonal or cubic symmetry system.
