is a prerequisite[6-7]. Grain refinement by severe plastic deformation has been known as a potential and important tool for high strain rate or low temperature superplasticity[8-9]. Research shows that most... is revealed in Fig.3. BY comparing Fig.3 with Fig.1, specimen 1 exhibits grain refinement significantly in the plastic deformation due to DRX. An important basic feature of GBS is that all grains......
, Fuzhou 350002, China) Abstract:The behavior of flow stress of Al sheets used for pressure can prepared by different melt-treatment during plastic deformation at elevated temperature was studied..., and an Arrhenius relationship with the temperature, which implies that the process of plastic deformation at elevated temperature for this material is thermally activated. Compared with the Al pieces prepared......

: Severe plastic deformation layer was synthesized on the surface of Super304H stainless steel by surface shot peening. The microstructures and properties of plastic deformation layer were characterized... and discussed. The results show that the grain of surface layer of Super304H stainless steel is refined with high density of dislocations or stacking faults by plastic deformation after shot peening......

%, 83%, 87% and 90%, respectively. The corrosion properties of different deformed AZ80 samples were studied by galvanic test in 3.5% NaCl solution. The results show that plastic deformation could... alloys. For AZ80 alloys, the smaller the grain size is, the more homogeneous the structure is, and the better the corrosion resistance is. Key words: corrosion property; plastic deformation; AZ80......
