摘要

摘要: 通过实验方法优化得到了粉末床激光熔化成形H13钢的工艺参数，并研究了成形样件的微观组织和拉伸性能。通过实验得到了H13钢单道成形的优化工艺区间：激光功率225 ~ 325 W，扫描速度600 ~1200 mm/s，通过块体实验得到优化的工艺参数为：激光功率275 W，扫描速度900 mm/s，扫描间距0.08 mm。微观组织显示为柱状晶粒，晶粒的宽度约为3 ~ 5 μm，长度约为10 ~ 40 μm。在优化工艺参数下成形试样的室温抗拉强度高达1 761 MPa，延伸率为2.72%。

Abstract: The processing parameters of H13 steel formed with laser-powder bed fusion were optimized through experimental methods, and the microstructure and tensile properties of the formed samples were studied. The optimal processing interval of H13 steel single track forming is obtained through experiments: laser power 225～325 W, scaning speed 600～1200 mm/s. The optimal processing parameters obtained through the block experiment are: laser power 275 W, scanning speed 900 mm/s, hatch space 0.08 mm. The microstructure shows columnar grains with a width of about 3～5 μm and a length of about 10～40 μm. Under the optimal processing parameters, the tensile strength at room temperature is as high as 1 761 MPa and the elongation is 2.72%.
