| 摘 要： | 采用激光烧结成形技术研究了不同工艺参数对Fe-16%Ni金属粉末选区激光烧结成型件微观结构和致密性的影响。结果表明,随着脉冲宽度、扫描速度和铺粉厚度的增加,烧结后试样的密度先增加然后减少,随着扫描间距的增加,烧结后试样的密度减小。当脉冲宽度0.7 ms,扫描速度1000 mm/min,铺粉厚度0.15 mm,扫描间距0.15 mm时,烧结成型件成型质量较好。

| Abstract: | Effect of process parameters on density and microstructure of sintered part of Fe-16% Ni metal powder fabricated by selective laser melting was studied.The results show the density of the sintered part firstly increases and then decreases with increasing of the scanning speed,laser pulse width,powder layer thickness and the density decreases with increasing of the scanning interval.Moreover,the sintered parts with the good forming quality are obtained when the laser pulse width,scanning speed,the powder lay... |
