摘要
研究了Al含量为27%～45%的高铝锌基合金的组织和性能,通过对合金采用金相显微镜、SEM、EDS及XRD方法检测,结果表明,随Al含量提高,高Al锌基合金中α相数量增多、细化及其固溶Zn、Cu元素的溶解度增加,固溶强化作用增强,同时α+η共析体数量减少、细化以及多种硬质点相产生,使ZA40合金力学性能、磨损性能明显提高。
The metallurgical microscope, scanning electron microscope （SEM）, energy disPersive spectrometer （EDS） and X-ray diffraction （XRD） were employed to investigate the microstructure and properties of high aluminum zinc-based alloys with different AI contents from 27 to 45 percent. The results show that with the increasing of Al content, the quantity of α phase in high-aluminum zinc-based alloys increases and the grains are refined, the solubility of Zn and Cu are enhanced and the solution strengthening effect improves. At the same time, the quantity of α＋η eutectoid phase decreases and fines as well as many kinds of hard phases appear, which result in the obvious improvement of the mechanical properties and abrasive resistance of the alloy.
