چکیده
An Al8Co19Cr23Fe32Ni18 high-entropy alloy with a solid solution of Al was prepared, and its pitting corrosion resistance in 0.1 M NaCl high-temperature oxidation at 1273 K were assessed. The potential this is lower than that the Al-free Co19Cr23Fe40Ni18 alloy, although higher. decrease owing to addition attributed surface oxide film nitride inclusions metal matrix. For potentiodynamic polarization 1 H2SO4 improved without decreasing resistance.

High Temperature Oxidation and Corrosion Properties of High Entropy Superalloys
The present work investigates the high temperature oxidation and corrosion behaviour of high entropy superalloys (HESA). A high content of various solutes in HESA leads to formation of complex oxides, however the Cr and Al activities of HESA are sufficient to promote protective chromia or alumina formation on the surface. By comparing the oxidation and corrosion resistances of a Ni-based supera...
متن کاملTHE OXIDATION RESISTANCE OF HIGH ALUMINUM HEAT RESISTANT STEELS
Abstract: In this research, the oxidation behaviour of high Aluminum heat resistant steel (%25Cr,%20Ni,%8Al) hasbeen evaluated at the temperature range of (1000-1300ºC).The results showed that there was no countinous healinglayer on the surface of the alloy when Al increased up to %5.5 and the oxidation resistance of steel decreased due toformation of spinel oxides on the surface.By increasing ...
متن کاملResistive Memory for Harsh Electronics: Immunity to Surface Effect and High Corrosion Resistance via Surface Modification
The tolerance/resistance of the electronic devices to extremely harsh environments is of supreme interest. Surface effects and chemical corrosion adversely affect stability and operation uniformity of metal oxide resistive memories. To achieve the surrounding-independent behavior, the surface modification is introduced into the ZnO memristors via incorporating fluorine to replace the oxygen sit...
متن کاملHigh-velocity deformation of Al0.3CoCrFeNi high-entropy alloy: Remarkable resistance to shear failure
The mechanical behavior of a single phase (fcc) Al0.3CoCrFeNi high-entropy alloy (HEA) was studied in the low and high strain-rate regimes. The combination of multiple strengthening mechanisms such as solid solution hardening, forest dislocation hardening, as well as mechanical twinning leads to a high work hardening rate, which is significantly larger than that for Al and is retained in the dy...
