The effect of pulsed electron beam treatment (density of energy 10, 30, and 50 J/cm² and pulse times 50 and 200 µs) on the microstructure and functional properties of the Al-5.4Si-1.3Cu alloy is traced via exploring its microhardness, wear resistance and microstructure. The research pointed out the wear resistance of the alloy irradiated with pulsed electron beam to be 197% higher than the same characteristic of the untreated material. A maximal microhardness increase was recorded for following electron beam treatment parameters: 30 J/cm², 200 µs and 50 J/cm², 50 µs; the values of microhardness were as high as 860 MPa and 950 MPa, respectively. Key factors responsible for better wear resistance and higher microhardness in the samples treated with a pulsed electron beam were suggested to be silicon and intermetallic compounds, dissolving in the molten surface, a cellular nano-dimensional structure, resulting from rapid solidification, and nano-dimensional particles of silicon and multi-element compounds.

通过探索脉冲电子束处理（能量密度分别为10、30和50 J / cm ²以及脉冲时间分别为50和200 µs）对Al-5.4Si-1.3Cu合金的组织和性能的影响，可以对其进行追踪。显微硬度，耐磨性和显微组织。研究指出，脉冲电子束辐照的合金的耐磨性比未处理材料的相同特性高197％。最大显微硬度增加被记录为下列电子束处理参数：30J /厘米²，200微秒和50J /厘米²，50 µs; 显微硬度值分别高达860 MPa和950 MPa。认为在用脉冲电子束处理的样品中导致更好的耐磨性和更高的显微硬度的关键因素是硅和金属间化合物，溶解在熔融表面，快速固化产生的蜂窝状纳米结构和纳米级硅和多元素化合物的颗粒。
