英文摘要The effects of laser energy densities on microstructures and mechanical properties of AlSi10Mg samples fabricated by pulsed selective laser melting (P-SLM) were studied. Scanning electron microscope, transmission electron microscope, X-ray diffraction, Vickers hardness tester and electronic testing machine were used for analysis and measurement of microstructures, phases and mechanical properties of the samples, respectively. The results show that fine cellular microstructures are composed of alpha-Al, eutectic Si, and secondary Si. Moreover, the microhardness values of the specimens perpendicular to the building directions fluctuate between HV(0.1)110 similar to HV(0.1)130 while those of the specimens along the building directions decrease with increasing building heights. Finally, comparison of the mechanical properties of P-SLM and casting samples were discussed, the better mechanical properties of P-SLM samples were showed than those of the casting samples, which can be attributed to solid solution strengthening, grain refinement strengthening, dislocations strengthening and second-phase strengthening.
