In dieser Monographie werden Grundlagen und neueste Erkenntnisse über die Konstitution des Eisens und seiner Legierungen dokumentiert. Gerade wegen seiner Vielseitigkeit ist Eisen das technisch wichtigste Material und trotz jahrtausendelanger Verwen

At the 10 at% limit of C and N interstitial solubility in γ-Fe the atomic volume crosses the critical volume separating the low-spin and high-spin states. This suggests that the lower energy state of the FCC solid solutions should be low-spin. This

Fe and its alloys exhibit magnetic properties that range from simple ferromagnetic ordering in the bcc phase to moment-volume instabilities in the fcc phase. In the present study we give an account of the stabilities of the structural phases of Fe an

The ferromagnetic invar effect in f.c.c. 3d-transition metal alloys spans an (s+d) valence electron concentration range of 8.6 ≤ e/a ≤ 9.5. The maximum spontaneous magnetostriction associated with the invar effect occurs at e/a8.7. For e/a ≤ 8.

Based on experimental results of high temperature thermal expansion, paramagnetic neutron scattering, considerations of the relative stability of the various phases of elemental Fe and total energy calculations, we discuss the interrelated aspects of

We measured the thermal expansion and the specific heat of TixFe100-x alloys with x = 30.5, 32.5 and 35, all with hexagonal C14 laves phase structure (MgZn2) like TiFe2, and determine the temperature dependence of the magnetic contributions to the th

The substitution of Fe by Mn in the bcc ferromagnetic system Cr75Fe25 decreases the Curie temperature and eventually destroys long range FM order at 3 at% Mn. At higher Mn concentrations antiferromagnetic order sets in. Resistivity measurements, toge

The addition of small amounts of Cu to Mn stabilizes the fcc phase in Mn (γ-Mn) in a broad temperature range which is otherwise stable in a narrow limit around 1400 K. These alloys undergo an fcc-fct transition on cooling which is accompanied by an

Anti‐Invar behavior in a material can be characterized by an anomalously large and a weak temperature‐dependent thermal‐expansion coefficient, when compared to the respective Gruneisen lattice expansion. It is just the opposite of the Invar eff
