Abstract

The microstructure and properties of the Cu-12Sn-4Ni alloy were analyzed by incorporating varying amounts of the rare earth element cerium. The study compared the alloy‘s microstructure, hardness, strength, friction, and wear. The results showed that adding 0.04 % of rare earth cerium refined the grain size of the Cu-12Sn-4Ni alloy from 75 μm to 200 μm to 75 μm to125 μm. The hardness of the alloy increased by 22.78 % to 135.897 HV 0.1 after adding cerium, and the tensile strength of the alloy reached its highest peak at 452.08 MPa, with an elongation of up to 64.735 % after fracture. Additionally, the wear rate of the material decreased by about 38.6 % to 1.61×10⁻⁵ mm³/mm. In conclusion, the addition of the rare-earth element cerium successfully improved the structure and properties of the Cu-12Sn-4Ni alloy, leading to enhanced hardness, strength, and wear resistance.

稀土铈对Cu-12Sn-4Ni合金结构和性能的影响

通过添加不同量的稀土元素铈，分析了Cu-12Sn-4Ni合金的组织和性能。该研究比较了合金的微观结构、硬度、强度、摩擦和磨损。结果表明：添加0.04%的稀土铈可使Cu-12Sn-4Ni合金的晶粒尺寸从75 μm细化到200 μm和75 μm细化到125 μm；加入铈后，合金的硬度提高22.78%，达到135.897 HV 0.1，合金的抗拉强度在452.08 MPa时达到峰值，断口伸长率高达64.735%。此外，材料的磨损率降低了约38.6%，为1.61×10−5 mm3/mm。综上所述，稀土元素铈的加入成功改善了Cu-12Sn-4Ni合金的组织和性能，提高了合金的硬度、强度和耐磨性。

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
