Chemical and grain-size analysis of AlSi10Mg alloy powder has been performed. It has been found that the powder particles are generally nonspherical, with a significant number of inclusions in the form of satellites. The particle size distribution ranges from 5 to 60 μm. The presence of conglomerates up to 70 μm in size is observed. Studies on the effect of scanning parameters on the tensile strength and relative elongation of the samples have been performed. It has been found that, in the range of the scanning velocity from 910 to 930 mm/s, local mechanical minima are observed. In order to optimize the scanning parameters, complex quality parameters are used. The greatest desirability from the standpoint of obtaining the maximum strength and plasticity of the material consists in a combination of the scanning parameters: laser power of 350 W, scanning pitch of 0.19 mm, scanning velocity of 980 mm/s at a layer thickness of 50 μm. The test results of cylindrical samples made at the angles of 0° and 90° with respect to the construction platform are presented. [ABSTRACT FROM AUTHOR] |
