單向纖維晶強化超高強度鋼絲制備

Fabrication of Unidirectional Fibrous Crystal Reinforced Super High Strength Steel Wire

  • 摘要: 提出了將連續定向凝固技術與低溫強塑性加工相結合,制備連續纖維晶強化超高強度鋼絲的思想,并在實驗室成功地制備了具有單向柱狀晶組織的鑄鐵與不銹鋼鑄棒,證實了連續定向凝固技術用于鋼鐵材料是可行的。

     

    Abstract: In order to enhance greatly the strength of steel wires used for suspension bridge, stayed-cable bridge and tyre cord,a new method combining continuous unidirec-tional solidification process with low temperature (under recrystallization temperature) large deformation plastic working is presented for producing super high strength steel wires. The cast iron and stainless steel continuous cast ingots with unidirectional columnar crys-tals have been fabricated successfully. It is confirmed that the continuous unidirectional solidification process can be used for the forming of iron and steel materials.
