Asymmetric Rolling of Twin-roll Cast Al-5.5Mg-0.3Cu Alloy Sheet : Mechanical Properties and Formability

Annealing behavior of severely deformed IF steel via the differential speed rolling method

“…Unfortunately, a batch processing nature of SPD methods might limit the commercial applications. To overcome the industrial demerit of SPD methods, the differential speed rolling (DSR) technique whose deformation mode was shear has been suggested in order to achieve grain refinement in a variety of metallic materials [5][6][7][8]. Thus, the DSR technique would be the method suitable for imparting intense plastic strain by passing the samples repeatedly through two rolls that rotated in two different speeds.…”

Microstructure evolution and mechanical properties of ultrafine grained IF steel via multipass differential speed rolling

“…3 a , the microstructure comprised the elongated coarse subgrains. The band-like structure was well developed, which was typical of the metallic materials through severe plastic deformation 18,19. Accordingly, most of the initial equiaxed grains shown in Fig.…”

“…The band-like structure was well developed, which was typical of the metallic materials through severe plastic deformation. 18,19 Accordingly, most of the initial equiaxed grains shown in Fig. 1 were prone to be readily elongated after deformation so as to accommodate the plastic shear strain, resulting in an elongated band structure with a width of y4 mm.…”

Temperature rise during differential speed rolling

“…However, the batch processing of SPD methods limited their practical applications. A differential speed rolling (DSR) where intense plastic strain was induced by the different speeds of the rolls with an identical dimension has been regarded as a promising method that provided the possibility to overcome the main drawback of SPD techniques [4]. It was reported that the temperature rise of the sample during deformation was pronounced due to the severe plastic work and frictional heat generated between the roll and sample [5].…”
