Microanalysis of Precipitation Processes in the Alloy 33 (Fe-Ni-Cr-Mo-N)

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...

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

Calculated oscillation periods of the interlayer coupling in Fe/Cr/Fe and Fe/Mo/Fe sandwiches.

Investigations of Surface Dissolution on Fatigue Crack Nucleation in Ni - 22 Cr - 2 Fe Alloy

Ni-Cr-Fe alloy specimens were fatigued in a hydrochloric acid solution cell at pH 5.6 ±0.1. Results show that the number of surface slip bands forming, extending, and widening increased with the number of cycles. Results also indicated that, initially, cracks initiated as transgranular features but took on intergranular forms as the number of cycles increased.
