这一结果背后的理论是，塑性变形发生在铜的原子平面上。因此，铜原子平面内

Theory behind this result is that plastic deformation occurs in the plane of the copper atoms. Accordingly, dislocations plane copper atoms increases, and with increasing amounts of cold work, the dislocation density increases. Eventually, the accumulation of dislocations at the grain boundaries, and limit any further position on the wrong atomic plane. It increases the yield strength of copper, tensile strength and hardness, but reduces the ductility.

The theory behind this result is that plastic deformation occurs on the atomic plane of copper. As a result, the misalignment within the copper atomic plane increases, and as the amount of cold power increases, the misalignment density increases. Eventually, the misalignment will accumulate at the crystal boundary and limit any further misalignment on the atomic plane. The yield strength, tensile strength and hardness of copper are improved, but their ductility is reduced.

The theory behind this result is that plastic deformation occurs on the atomic plane of copper. Therefore, the dislocation density in the plane of copper atom increases with the increase of cold energy. Ultimately, dislocations accumulate at grain boundaries and limit any further dislocations in the atomic plane. The yield strength, tensile strength and hardness of copper are increased, but its ductility is reduced.<br>
