austenitic stainless steeldiffusionluminescencenickeloxidationscanning electron microscopysurface structurethermal analysis/ nickeloxidationA series of experimental austenitic alloys has been produced in which the nickel content ranges from 14 to 43%, with constant levels of 20%Cr, 1%Mn and 0.5%Si. A ...
The possible distribution of these planes types, based on information from the single-surface trace analysis, had a high rank correlation coefficient, 0.925, with previous data from nickel which was based on a two-surface, full boundary planes analysis. This is a preview of subscription content,...
Withnickel being a cornerstoneof the cleantech transition — for both EV batteries and large-scale energy storage systems — even though it’s already produced at a pretty big scale for other things (like stainless steel), its supply will need to grow orders of magnitude larger. Tesla, General...
The metallographic structure of the eight experimental materials is shown in Fig.1. It can be seen from the figure that Cr changes the microstructure of the matrix. The Cr content primarily affects the proportion of bainite in the steel. The W1 structure is essentially ferrite with a very smal...
Nevertheless, due to the interaction between corrosive media and metals, these substances degrade once they are incorporated into the human body. Adjacent to the implants, inevitable byproducts of the corrosion reactions are detrimental to the health of the vital organs. Nickel (Ni) ions discharged...
The required amount of ammonium molybdate tetrahydrate (99%, Sigma-Aldrich) and nickel (II) nitrate hexahydrate (99%, Sigma-Aldrich) was first dissolved in water and then added dropwise to the zeolite. The mixture was then stirred for 0.5 h at 25 °C. Water was removed via rotary ...
Titanium has been added to ferritic stainless steels to combat the detrimental effects of intergranular corrosion. While this has proven to be a successful strategy, we have found that the resulting Ti-rich inclusions present on the surface play a significant role in the initiation of other forms...
