It is characterized by recurrent seizures, which are brief episodes of signs or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.

It has been widely accepted as a ＂green＂ technology due to its energy efficiency and environment friendliness, and is considered the most significant development in the field of material joining over the past two decades. Friction stir processing （FSP） was later developed based on the basic principles of FSW. FSP has proven to be an effective and versatile metalworking technique for modifying and fabricating metallic materials.展开更多
