The Rendering from the Periodic System of the Elements on the stability, elastic, and electronic properties of M2AC phases
Erxiao Wu, Yiming Zhang, Mian Li +4
MAX phases are nanolaminated ternary materials that combine metallic and ceramic properties. Currently, the A-site elements replacement in traditional ones by later transition-meta…
Synthesis and thermal expansion of chalcogenide MAX phase Hf2SeC
Xudong Wang, Ke Chen, Erxiao Wu +7
Thermal expansion of MAX phases along different directions tended to be different because of the anisotropy of hexagonal crystals. Herein, a new Hf2SeC phase was synthesized and co…
A statistical analysis of pores and micro-cracks in nuclear graphite
Qing Huang, Hui Tang
Microstructure characterization is of great value to understanding nuclear graphite's properties and irradiation behavior. However, graphite is soft and could be easily damaged dur…
