对工业纯Cu和纯Fe冷拔变形,研究大变形下性能与组织的变化.研究表明,在大变形的情况下,与退火态相比其抗拉强度、硬度和电阻率均有提高.纯Cu的抗拉强度、显微硬度和电阻率在截面真应变4.621时分别提高80.5%、42.5%和8.00%;纯Fe的抗拉强度、显微硬度和电阻率在截面真应变3.544时分别提高198.2%、54.4%和3.16%.随真应变的增大,Cu、Fe抗拉强度均明显增加,Fe表现的尤为突出.Cu的硬度和电阻率在应变增加到一定值后基本保持不变,而Fe的硬度和电阻率与抗拉强度一样始终随应变的增加而增加.用纯Cu和纯Fe在截面真应变3.544时的抗拉强度计算了Cu-11.5%Fe原位复合材料在相应变形下的抗拉强度,计算结果与测量值相符.
