摘要
通过试验分析研究了 40 Cr钢的组织与冷态成型性能之间的关系 ,提出了获得最佳冷态成型性能组织的淬火 -循环球化退火工艺。该工艺可使钢具有硬度低、塑性变形抗力低、工艺塑性较高的特点 ,可满足冷态成型工艺对材料提出的软化处理的技术要求。
The relationships between microsturcture and cold deformed property of 40Cr steel have been studied by experimental analysis investigation.The heat treatment process of guenching cyclic sphereidized annealing for obtaining sturcture with optimum cold deformed property was suggested.Through this process the characters with lower hardness,lower plastic deformation resistance and better processing plastic of the steel can get.The properties of this steel can meet the requirement of cold deformed process for materials.
