Summary:

Different anelastic phenomena are discussed in this book with respect to iron-based binary and ternary alloys and intermetallic compounds of Fe3Me type, where Me are α-stabilizing elements Al, Ga, or Ge. An introduction into anelastic behavior of metallic materials is given, and methods of mechanical spectroscopy and neutron diffraction are introduced for the better understanding of structure-related relaxation and hysteretic phenomena.
