APPLICATION OF MAGNETIC METHODS TO THE STUDY OF THE STRAIN STATE OF NICKEL-BASED SUPERALLOYS

DOI: 10.17804/2410-9908.2017.1.006-012

Strain-induced magnetism is observed after severe high-temperature deformation in a gas turbine blade made from nickel-based superalloy. The appearance of ferromagnetic ordering in the initially paramagnetic alloy results from the formation of magnetic clusters inside the cuboids of the strengthening intermetallic phase (Ni₃Al). The change in the values of magnetic susceptibility correlates with the change in the level of dynamic stresses and the number of stacking fault defects in different parts of the blade.
