In this study, aluminium-silicon alloy AlSi10Mg powder of spherical morphology was mixed with niobium carbide powder had irregular morphology in weight percentages of 2, 4, 6 and 8 and processed in a planetary ball mill apparatus. The optimal conditions for powder processing were a mixing time of 1.95 h and a speed of 71 RPM without milling balls. The use of milling balls was avoided to maintain the morphology of AlSi10Mg from degradation and improve the flowability of composite powder. To evaluate the flowability of processed powders, flow properties such as apparent density, tapped density, Hausner’s ratio, Carr index, static angle of repose and Hall flow rate were determined. Selective laser melting was used to fabricate AlSi10Mg composite specimens with varying percentages of niobium carbide. Finally, at 6% niobium carbide, the selective laser melting cube specimen had a maximum relative density of 99.21%.

在这项研究中，球形形态的铝硅合金 AlSi10Mg 粉末与具有不规则形态的碳化铌粉末以 2、4、6 和 8 的重量百分比混合，并在行星球磨机设备中加工。粉末加工的最佳条件是 1.95 小时的混合时间和 71 RPM 的速度，没有研磨球。避免使用研磨球以保持 AlSi10Mg 的形貌免于降解并提高复合粉末的流动性。为了评估加工粉末的流动性，确定了流动特性，例如表观密度、振实密度、豪斯纳比、卡尔指数、静态休止角和霍尔流速。选择性激光熔化用于制造具有不同百分比碳化铌的 AlSi10Mg 复合材料试样。最后，在 6% 的碳化铌下，
