wire room

The microstructure of copper clad aluminum wire by drawing at room temperature is vimineous grain as fibril shape from prime equiaxed grain.

经室温拉拔的铜包铝线的显微组织是纤维状细长晶粒，晶界面积增大系数与形变量近似地成正比。

Compared to the normal wire drawing technology in room temperature, the cryogenic wire drawing technology showed remarkable effect: tensile strength was improved nearly 400 MPa, micro vickers hardness was enhanced 74 HV 4.9N, in the meanwhile, toughness was almost changeless.

研究表明，在相同的拉丝条件下，与常温工艺相比，深冷工艺能大幅度提高钢丝的综合力学性能。抗拉强度进一步提高近400MPa，显微硬度进一步提高74HV4.9N，而抗扭次数及伸长率基本不变。
