ABSTRACT Nanocrystalline CoZn-ferrite was fabricated by a high-energy milling method by mixing Fe 3 O 4 +CoO+ZnO. The structural properties of the milled powder at different milling times were analysed so to ascertain the diffusion of CoO and ZnO into the tetrahedral and oct...

ABSTRACT The thermal stability of nanocrystalline Ni-Co-Fe-P coatings with phosphorus content up to 3.38 wt% prepared by pulsed electrodepostion was studied using XRD, TEM and DSC. It is found that multi-component alloying does improve the thermal stability of nanocrystalline coatings due to a “solution drag effect”. For nanocrystalline Ni-40.41%Co-6.16%Fe-1.63%P coating, P-atoms ...
