One-dimensional CdS nanocrystals have been prepared by solvothermal method using cadmium acetate as a cadmium precursor,elemental sulfur and Na2S,as a sulfur pr
The thermal features of the nanograin boundary were described by a developed thermodynamic model.Using the nanocrystalline Cu as an example,the pressure,the bul
6 mm thick ZK60 and ZK60-Y alloy plates were successfully friction stir welded (FSW) at a tool rotation rate of 1200 r/min and a traverse speed of 100 mm/min. F
