Abstract AITranslate

During high-temperature,high-reduction deformation,beryllium is susceptible to contamination by free impurity elements originating from the A3 and S45 steels used for pack rolling and superimposed rolling.Specifically,Fe and Si primarily reside on the surface layer of the deformed beryllium through ad-sorption,while Mn and C accumulate via diffusion.This study investigated the influence law of free impuri-ty content on the surface strength,hardness,and plasticity of deformed beryllium.Effective control of Fe/Si and Mn/C impurities was achieved through weak acid cleaning and ultrasonic cleaning,respectively.The results indicate that an increase in free impurity content significantly enhances surface strength and hard-ness but reduces elongation after fracture.As point defects,free impurities hinder dislocation movement and promote excessive grain refinement,which strengthens the material while simultaneously impairing its plasticity.Weak acid cleaning effectively reduces Fe and Si impurities,whereas ultrasonic cleaning signifi-cantly decreases Mn and C impurities.This research confirms that rational control of the free impurity con-tent in deformed bery-llium surface can achieve a balance between strength,hardness,and plasticity,provi-ding a theoretical and technical foundation for the preparation of high-performance beryllium materials.
