Al-10MgSi alloy was produced by additive manufacturing technique using selective laser melting. The processing parameters are optimized for printing an alloy using this technique. The microstructures, physical and mechanical properties of printed samples are tested using different characterization techniques such as optical metallurgical microscope, electronic balance and nano 25kN BISS instrument. The surface topography of the printed sample is entirely different from the surface topography of the alloy produced using other different processing techniques. The average density of the selective laser melting samples found to be reported as 2.59± 0.02g/cc. The microhardness of the sample is measured using Vickers hardness testing machine and the average micro Vickers hardness is reported as 128±3.14 HV1. The mechanical properties such as yield strength (YS) and ultimate compression strength (UCS) are measured using tensile cum compression testing machine. The YS of the compressed sample 1 is 190 MPa, sample 2 is revealed as 250 MPa, and the sample 3 is reported as 210 MPa. The UCS of compressed samples one, two and three are reported as 500, 320 and 350 MPa respectively. |
