چکیده
The in-situ observation of microstructural evolution under electron irradiation was performed in order to experimentally estimate the mobility vacancy and interstitial 316 stainless steel CoCrFeNi-base high entropy alloys. migration energy CoCrFeNiMn CoCrFeNiAl0.3 estimated be lower higher compared with that steel, respectively. While, those alloys seems almost same. increase is probably due a strong interaction between Al. positron annihilation analysis revealed vacancies might exist close Co Ni atoms In addition, could also captured by Mn Al CoCrFeNiAl0.3, electron- ion-irradiation at 400 300 °C up 1.5 dpa resulted precipitation intermetallic compounds, such as CoFe, NiFe CoCrFeNiMn, Ni3Al CoCrFeNiAl0.3. From these results, it suggested Co, Ni, Mn, affect HEAs, leading delay enhancement irradiation.

Point Defects in Nial Alloys under Pressure
We investigate the eeect of elevated pressures on the point defect ther-modynamics in NiAl alloys. A particular motivation for this study is due to the expected elimination of structural vacancies on the Al-rich side at high pressure. We employ the density functional theory to compute point defect energies as a function of pressure, which are in turn used as input to the Wagner-Schottky model. ...

متن کاملSuperior hydrogen storage in high entropy alloys
Metal hydrides (MHx) provide a promising solution for the requirement to store large amounts of hydrogen in a future hydrogen-based energy system. This requires the design of alloys which allow for a very high H/M ratio. Transition metal hydrides typically have a maximum H/M ratio of 2 and higher ratios can only be obtained in alloys based on rare-earth elements. In this study we demonstrate, f...
