Rapid anisotropy recovery in deformed FCC metals by high-density pulsed electric current treatment

The {101} texture of deformed face-centered cubic metals, such as 316 stainless steel and Ni-based alloy Inconel 718, was successfully alleviated by high-density pulsed electric current (HDPEC) treatment. Furthermore, the deformed grains recovered after the HDPEC treatment. The HDPEC induced the rapid dislocation motion and grain refinement that resulted in random grain orientation and equiaxed grain morphology, which led to anisotropy recovery in the deformed metals. This method provides a promising way to modify the microstructure of materials with short time and low cost, after forming or during service.

Automated summary

The {101} texture of deformed face-centered cubic metals can be alleviated by high-density pulsed electric current (HDPEC) treatment, which also leads to recovery of deformed grains, resulting in random grain orientation and equiaxed grain morphology to recover anisotropy in the deformed metals. This method provides a promising and cost-effective way to modify the microstructure of materials.
