Recrystallization, structure, texture and properties of pipe steel rolled at wide temperature range

摘要

Methods of complex X-ray and metallographic analyses have been used to investigate the influence of texture, thin structure and grain boundaries of coiled low-alloyed steel for gas-and-oil pipeline tubes after hot rolling on its mechanical properties. Finish rolling temperature changes in a wide range (T_(FR) = 89~0 C-53~0 C). Specifics of steel structure formation under conditions of dynamic (controlled rolling) and static (high-and-low temperature rolling) recrystallization have been found.
