一般控制轧制基本过程大致可由以下三个过程组成:1)奥氏体(γ)再结晶温度区域反复变形和再结晶使奥氏体晶粒细化;2)奥氏体未再结晶区或奥氏体和铁素体两相区中变形形成变形奥氏体或导入变形带;3)由以上两个过程得到细小的铁素体组织,再进一步分解生成低温相变组织。钢材
General control of the basic process of rolling can be roughly composed of the following three processes: 1) austenite (γ) recrystallization temperature region repeated deformation and recrystallization austenite grain refinement; 2) austenite non-recrystallization region or Austenite and ferrite in the deformation of the two-phase deformation of the formation of austenite or deformation zone; 3) obtained by the above two processes of ferrite, and then further decomposition of low-temperature phase transition organization.
