Effect of Welding Parameters on Nanostructured Fe-(C, B)-(Cr, Nb) Alloys

Effect of Wet and Dry Conditions on Wear Behavior of Amorphous Coating of Fe-Cr-Mo-Nb-C-B

Recently, wear resistant properties of metallic glasses has attracted a lot of interest. Because the surface of metallic glasses are prone to phase transformation, finding the effects of test condition on structure and wear behavior of metallic glasses is important. In this research, by using an automated electrospark deposition (ESD), a layer of Fe51Cr18Mo7B16C4Nb4 was deposited on AISI 316l s...

Effect of pressure on phase stability in Fe-Cr alloys

0-π oscillations in nanostructured Nb/Fe/Nb Josephson junctions

The physics of the π phase shift in ferromagnetic Josephson junctions enables a range of applications for spin-electronic devices and quantum computing. We investigate transitions from “0” to “π” states in Nb/Fe/Nb Josephson junctions by varying the Fe barrier thickness from 0.5 nm to 5.5 nm. From magnetic measurements we estimate for Fe a magnetic dead layer of about 1.1 nm. By fitting the cha...

Crystallization behavior and magnetic properties of Cu-containing Fe–Cr–Mo–Ga–P–C–B alloys

Multicomponent Fe65.5Cr4Mo4Ga4P12C5B5.5 amorphous alloy is known to have good soft magnetic properties combined with large glass-forming ability. Searching for a nanocrystalline structure that could improve its magnetic properties, Cr and Mo were partially substituted by Cu. The devitrification process of Cu-containing alloys shows an additional broad crystallization event that can be described...

Phase transitions in nanostructured Fe–Cr–Ni alloys prepared by mechanical alloying

Phase transition of Fe–18Cr–8Ni, Fe–15Cr–15Ni and Fe–15Cr–25Ni alloys during mechanical alloying (MA) and after subsequent annealing as studied. For Fe–18Cr–8Ni and Fe–15Cr–15Ni the resulting structure by MA was a nanostructured single-phase BCC solid solution ( ) which iffers from that predicted from equilibrium phase diagram. Furthermore, the equilibrium structure was not achieved after heat ...
