Abstract: | Results of an experimental research into evolution of structure and micro hardness hard magnetic alloy Fe-30Cr-8Co-0.7Ti-0.5V-0.7Si at complex two-level in isothermal conditions on the circuit deposittorsion at various temperatures in single-phase ( are given. It is revealed that deformation results in transformation of coarse-grained structure in fine-grained in all volume of the sample, however the generated structure is non-uniform on section of a sample. In an active zone of deformation near to mobile it is brisk the microcrystalline layer with the size of grains about 5 microns which thickness poorly depends on temperature is formed. In process of removal from an active zone of deformation the size of grains is increased, and micro hardness decreases. |
