Problems solved by technology

These methods have some effect, but these methods do not make a significant improvement in the strength of the material
Moreover, there are still a large number of grain boundary defects in the material, resulting in a large number of dislocations and slips, resulting in poor interface bonding, large gaps between grain boundaries, and poor grain size uniformity.
