Mechanical Properties of The Hard Magnetic Alloy Fe-23wt.%Co-30%Cr In Different Structural States

摘要

The mechanical properties of samples of Fe-23wt.%Co-30%Cr alloy having different structural phases in a nanocrystalline and coarse grained states were determined experimentally. Different coarse-grained structures were obtained by annealing at temperatures ranging from 540 to 1300 ℃. Subsequently, severe plastic deformation by high-pressure torsion at room temperature, produced the nanocrystalline structure. The nanocrystalline samples exhibited increases in strength and plasticity in comparison with relevant coarse grained samples.
