摘要/Abstract

摘要： 采用真空熔炼并经均匀化退火、热轧、固溶、冷轧和时效处理工艺制备Cu-xNi-3Ti-0.1Zr(x=2、4、6)合金,通过X射线衍射仪、光学显微镜和扫描电镜对合金的析出相进行表征和分析。结果表明,Ni的加入能够显著提高合金的导电率,且对其硬度的影响也同样显著。Ni在Cu-xNi-3Ti-0.1Zr合金中主要以CuNiTi相存在;Ni的加入导致合金中大量CuNiTi相的析出,降低了基体中Ti的固溶度,使合金的晶格畸变程度降低,从而提高了合金的导电率。但随着Ti的析出,Ti对合金的强化效果减弱,从而导致合金的硬度降低。在本试验工艺下,Cu-xNi-3Ti-0.1Zr(x=2、4、6)合金在500 ℃时效的峰值硬度分别为295、231、201 HV0.5。

Abstract: Cu-xNi-3Ti-0.1Zr (x=2, 4, 6) alloy was prepared by vacuum melting and homogenizing annealing, hot rolling, solution treatment, cold rolling and aging treatment. The precipitates of the alloy were characterized and analyzed by means of X-ray diffractometer, optical microscope and scanning electron microscope. The results show that the addition of Ni can significantly increase the electrical conductivity of the alloy, and the effect on the hardness is also obvious. Ni exists mainly in CuNiTi phase in the Cu-xNi-3Ti-0.1Zr alloys; The addition of Ni leads to the precipitation of a large amount of CuNiTi phase in the alloy, which decreases the dissolving degree of Ti in the solid solution matrix and reduces the degree of lattice distortion of the alloy, thus increasing the electrical conductivity. However, with the precipitation of Ti element, the strengthening effect of Ti on the alloy is weakened, which leads to the decrease of the hardness of the alloy. The peak hardness of the Cu-xNi-3Ti-0.1Zr (x=2, 4, 6) alloys aged at 500 ℃ is 295, 231 and 201 HV0.5, respectively.

Key words: Cu-Ni-Ti-Zr alloy, CuNiTi phase, microstructure, hardness, electrical conductivity
