摘要: In this study, we report a comprehensive assessment on the elastic and electronic properties of 792 possible MAX (Mn+ 1AXn) phases with n= 1–4 using ab initio methods. These crystals are then screened based on their elastic and thermodynamic stability resulting in a large database of 665 viable crystals. All the experimentally verified MAX phases passed the screening. Various correlations among and between them are fully explored. In particular, the key elements in the interdependence between the elastic properties together with …
