Webb1 juli 1999 · The discovery of the Invar effect has stimulated many experimental and theoretical studies of this phenomenon, and a number of theoretical models have been … Webb1 aug. 2024 · The Invar effect in the non-equiatomic Fe 63 Ni 32 Co 5 alloy is of step-type with nearly zero TEC over a wide temperature range (from room temperature to 120 °C) below its Curie temperature. The equiatomic FeNiCo alloy shows a peak-type Invar effect in a very narrow temperature range (from ∼675 °C to ∼730 °C) with relatively low TECs.

Webb8 apr. 2004 · Investigating bcc Fe-Co and fcc Fe-Pt(Pd) alloys which exhibit large values of the volume magnetostriction in a certain range of chemical composition and concomitantly an anomalously low thermal expansion coefficient (Invar effect), we find that this behavior is due to changes in the electronic structure induced by the effects of magnetic disorder … Webb15 juni 2024 · In this study, atomic-scale origin of the Invar effect, which is nearly-zero thermal expansion observed in the Invar alloy Fe 65 Ni 35, was investigated by reverse Monte Carlo analysis using complementary data sets of extended x-ray absorption fine structure and x-ray diffraction. Therefore, the Fe-Fe pairs dominantly contribute to the … Webb15 juli 2024 · The Invar effect, which refers to magnetic alloys having an anomalously small thermal expansion, has been under extensive investigations over the past century. However, study on the thermal expansion of clusters and their Invar effect is still lacking.
