Deformation-induced dissolution of borides in FCC Fe–Ni alloys

Abstract

Deformation-induced dissolution of amorphous and crystal boron and also of orthorhombic boron nitride in face centered cubic (FCC) Fe-Ni alloys matrix has been investigated with the methods of Mössbauer spectroscopy, magnetic susceptibility and X-ray diffraction analysis by compression shear in Bridgman anvils. The formation of boron solid solution in a Fe-Ni alloy matrix has been revealed in the mechanosynthesis process. Growth of inner effective magnetic field, Curie point and crystal lattice period of invar alloys has been detected. Conclusion about the formation of supersaturated crystal boron interstitial solid solution in FCC Fe-Ni alloys has been made.
