Texture Evolution in Low Carbon Steel Fabricated by Multi-directional Forging of the Martensite Starting Structuree
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
متن کاملMicrostructural evolution during recrystallization in hot rolled Aluminum Alloy 1050
The evolution of texture as a function of recrystallization has been characterized for hot-rolled AA1050. Samples prepared from a hot rolled sheet were annealed isothermally for sufficient time to allow complete recrystallization. The spatial orientation variation within the deformed microstructure of nucleation, growth and orientations of recrystallized grains is examined. The microstructural ...
متن کاملThe recrystallization of copper single crystals deformed at 4.2 K
The deformation of copper single crystals at 4.2 K occurs by a sequence of slip, twinning and slip in the twinned structure. Subsequent annealing of the deformed structures obtained at various points at this sequence of deformation permits the detailed nature of the deformed and recrystallized states to be related in a unique fashion. Material recrystallized from structures obtained prior to th...
متن کاملInterface Anisotropy and its Effect on Microstructural Evolution During Coarsening
The driving force for coarsening is provided by the excess interfacial free energy. In a system with isotropic interface energies, classical coarsening theories can predict the evolution of the sizes of spherical crystals. However, if the interfaces are anisotropic, crystal growth and shrinkage may be limited by the surface attachment/detachment rate, the motion of ledges, or the nucleation of ...
متن کاملMicrostructural Evolution of X45CrNiW189 Valve Steel During Hot Deformation
The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...
