单向纤维晶强化超高强度钢丝制备

Fabrication of Unidirectional Fibrous Crystal Reinforced Super High Strength Steel Wire

提出了将连续定向凝固技术与低温强塑性加工相结合，制备连续纤维晶强化超高强度钢丝的思想，并在实验室成功地制备了具有单向柱状晶组织的铸铁与不锈钢铸棒，证实了连续定向凝固技术用于钢铁材料是可行的。

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.
