摘要

摘要: 采用激光选区熔化技术制备18Ni300试样，通过SPSS(Statistical Product and Service Solutions)统计软件以及多种性能检测设备，着重研究激光选取熔化制备角度对尺寸、粗糙度以及致密度的影响关系。并对制备试样进行时效强化处理，研究时效强化对成型质量的影响。试验结果表明，无论采用什么制备角度，制备试样与原设计尺寸相比均出现缩小；在宽度方向上，随着制备角度的增加，尺寸呈上升趋势；厚度方向、尺寸呈下降趋势；粗糙度呈先增加后减小的趋势；而致密度呈现先减小后增大趋势。将试样进行时效强化热处理后，尺寸没有发生较大变化，而热处理后的粗糙度和致密度有明显的下降趋势。

Abstract: Selective laser melting has been applied to fabricating 18Ni300. Using SPSS（ Statistical Product and Service Solutions） and various testing equipment to study the dimensions,roughness and density of specimen with different fabrication angle. Meanwhile,ageing treatment was applied,and its influence on the quality and shape were analyzed. The result shows that the dimensions of specimen become smaller than the designed dimensions. The specimen becomes wider and thinner with the fabrication angle being larger. Roughness increases firstly and then decreases with the fabrication angle being larger. However,Density first decreases and then increases with the increase of the fabrication angle. Though ageing treatment cannot make any changes on the dimension of parts,it can result in the improvement on roughness but decrease of density.
