一般来说，位错与富Cu相之间的交互作用可分为两类：一类是“直接接触”的

Generally speaking, the interaction between dislocations and Cu-rich phases can be divided into two categories: one is the interaction of "direct contact", and the other is the interaction of "indirect contact". The former refers to the force exerted by the presence of different stacking fault energies or shear moduli between the precipitated phase and the matrix when the slip shift crosses the Cu-rich precipitated phase; the latter refers to the sliding dislocation due to the precipitated phase. The force exerted in the coherent strain field caused by the lattice mismatch between the matrix and the matrix is ​​much larger than the size of the precipitated phase itself.

In general, the interaction between misplaced and rich Cu phase can be divided into two categories: one is the interaction of "direct contact" and the other is the interaction of "non-direct contact". The former refers to the force of force when the slip shift miscutts the rich Cu-out phase due to the difference between the delineation phase and the substation fault energy or shear modality, and the latter refers to the force that the slip misalme is subjected to when moving in the common grid strain field caused by the lattice misalization between the destruation phase and the substation, and the range of the common strain force is much larger than the size of the phase itself.

Generally speaking, the interaction between dislocations and Cu rich phases can be divided into two types: one is "direct contact" interaction, the other is "non direct contact" interaction. The former refers to the force caused by the different stacking fault energy or shear modulus between the precipitate and the matrix when the sliding displacement crosscuts the Cu rich precipitate; the latter refers to the force of the sliding displacement fault moving in the coherent strain field caused by the lattice mismatch between the precipitate and the matrix, and the scope of the coherent strain force is much larger than the size of the precipitate itself.<br>
