摘要: Abstract Discontinuous deformation in Al-Mg alloys has been investigated at 77 and 293 K. The serration appears on the stress-strain curves even K these specimens. magnitude of single crystals increases with increasing strain up to end stage II, then slightly decreases. After that, it becomes roughly constant III. formation coarse slip band is closely related serration. On other hand, polycrystals much larger than that crystals, fracture. Broad band-markings appear random polycrystals, each which causes a large results mentioned above are discussed terms process
