铜钛镧合金的组织与性能

Microstructures and Properties of the Cu-Ti-La Alloys

主要用金相显微镜分析和显微硬度测定法。研究了铜钛镧合金热处理后的组织与性能。镧可以提高合金的硬度;镧以化合物形式存在合金中,当合金含镧量少时,镧主要分布在晶界及球状颗粒中。

The microstructure and properties of the Cu-Ti-La alloys after hcat treatment werestudicd by optical microscopy and microhardness test. The lanthanum can incrcase the hardness of the alloys. The lanthanum exists in the alloy in the form of compound.When lanthanum contcnt in the alloys is small, it distributcd mostly in grain boundaris and globular granules.
