Effect of Si on Corrosion of Fe-Cr and Fe-Cr-Ni Alloys in wet CO2Gas

Corrosion Performance of Fe-Cr-Ni Alloys in Artificial Saliva and Mouthwash Solution

Several austenitic stainless steels suitable for high temperature applications because of their high corrosion resistance and excellent mechanical properties were investigated as biomaterials for dental use. The steels were evaluated by electrochemical techniques such as potentiodynamic polarization curves, cyclic polarization curves, measurements of open circuit potential, and linear polarizat...

Corrosion performance of Ni-Cr-Fe alloys in geothermal hypersaline brines

The early development of the Salton Sea geothermal resource proved that carbon steel tubulars do not provide satisfactory service life in the high-temperature, hypersaline brines. A large-scale corrosion test was designed to find the most cost-effective alloys for completing these wells. A series of Ni-Cr-Mo alloys were tested over several years in three production wells and two injection wells...

Effect of pressure on phase stability in Fe-Cr alloys

Production and Characterization of Stainless Steel Based Fe-Cr-Ni-Mn-Si(-CO) Shape Memory Alloys

It is well known that the Fe based alloys can exhibit shape memory effect due to the y to E martensitic transformation. The effect may not be as striking as observed in the NiTi alloy but it might become attractive fkom the practical point of view. In this work, two compositions of Fe-Cr-Ni-Mn-Si(-Co) stainless steel based shape memory alloy, prepared by the VIM technique, will be presented. Th...

The Effect of Nickel Increasing and Aluminum Addition on Sulfidation Resistance of Fe-Ni-Cr Alloys (TECHNICAL NOTE)

In this research the effects of; increasing the amount of nickel and adding aluminum to create and prolong sulfidation resistance of Fe-Ni-Cr alloys have been investigated. Sulfidation tests were carried out at 1100°C in S/O bearing atmosphere. Prior to the tests, the specimens were annealed in argon at 1250°C for 8 hrs. Weight changes were measured and corroded deposits were analyzed byscannin...
