Therefore, the study of corrosion resistance of MAX phase materials in lead-based alloys has important reference value for the application of these materials in advanced nuclear power systems.
The wetting behavior between liquid metals and structural materials can qualitatively reflect the adsorption force of structural materials on liquid metal atoms.

According to the different forms of damage, material stiffness will be degradated and the corresponding material modulus will be multiply by as the new damaged material modulus.
Degradation of material modulus: (1) Fiber tension or compression : E11，G12，G13 (2) Matrix tension or compression : E22，E33，G12，G23 The damage parameter will change with the strain from one (represents the undamaged material) to zero (represents the completely failure material).
