Abstract
This study investigated the synergistic effects of Ti and Cr alloying elements on the microstructure, mechanical and wear properties of Cu-Zn manganese brasses. The simultaneous addition of Ni and Pb elements decreases the size of silicides and thus increases the yield strength of brass. The addition of Ti on the basis of Ni and Pb increases the content of silicides, and the generation of massive small-sized silicides increases the hardness and the wear resistance of brass. Cr element has refining effect on the size of silicides, and the smallest-sized and most uniformly distributed silicides induce the largest ultimate tensile strength and elongation. However, the simultaneous addition of Cr and Ti elements causes the agglomeration of silicides, and this results in poor ductility and wear resistance of brass.
本研究探讨了钛和铬合金元素对铜锌锰黄铜的微观结构、机械性能和磨损性能的协同效应。同时添加 Ni 和 Pb 元素会减小硅化物的尺寸，从而提高黄铜的屈服强度。在 Ni 和 Pb 的基础上添加 Ti 会增加硅化物的含量，生成大量小尺寸硅化物会提高黄铜的硬度和耐磨性。铬元素对硅化物的尺寸有细化作用，尺寸最小且分布最均匀的硅化物可产生最大的极限抗拉强度和伸长率。然而，同时添加铬和钛元素会导致硅化物团聚，从而使黄铜的延展性和耐磨性变差。
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
