Crystallization of Partially Amorphized Ni-Mo Alloy

Crystallization kinetics of Al±La±Ni amorphous alloy

The crystallization kinetics of an Al89La6Ni5 amorphous alloy were studied by thermal analysis. Both continuous heating and isothermal DSC traces showed that the Al89La6Ni5 amorphous alloy undergoes a two-stage crystallization process upon heating. The ®rst transformation, in which fcc-Al precipitates from the amorphous matrix, is a nucleation and three-dimensional di€usion-controlled growth pr...

Influence of temperature on passive film properties on Ni–Cr–Mo Alloy

Mo-Si-B Alloy Development

Alloys consisting of the phases α-Mo (Mo solid solution), Mo3Si, and Mo5SiB2 (“T2”) were fabricated by ingot and powder metallurgy. A novel powder-metallurgical processing technique was developed which allows the fabrication of silicide alloys with a continuous α-Mo matrix. In these alloys the relatively ductile and tough α-Mo matrix acts as a “binder” for brittle silicide particles. An alloy p...

Nanostructurization of Fe-Ni Alloy

Data about an effect of cyclic γ-α-γ martensitic transformations on the structure state of reverted austenite Fe-31.7 wt.% Ni-0.06 wt.% C alloy are presented. The effect of multiple direct γ-α and reverse α-γ martensitic transformations on fragmentation of austenitic grains has been investigated by electron microscopy and X-ray diffraction methods. An ultrafine structure has been formed by nano...

ELECTRONIC TRANSPORT IN Mo / Ni SUPERLATTICES

An experimental relationship between superconductivity, magnetism and localization is explored in short-wavelength (148 G A < 40A) sputtered Mo/Ni superlattices. A crossover to a superconducting state is observed for A < 9A consistent with the observed paramagnetic behavior when the Ni strata are four atomic layers thick, or less. All samples show localization effects at helium temperatures and...
