In this study, fully dense tungsten samples were additively manufactured and the micro-structure behavior was studied. A crack network with a spacing of 20μm up to 100μm was found in the designed samples. It was noticed that the laser scanning approach, which could customize the microstructure, affected the crack behavior in manufactured tungsten[1]. Different additive parameters were adopted to study the microstructure properties, but it was revealed that cracking is practically irresistible in AM (additive manufacturing). It might be achieved that cracking chain assembled because the cracks appeared in each laser fused path and then analogous in the surface-by-surface structure course.

增材制造纯钨的微观结构特征

在这项研究中,增材制造了全致密钨样品并研究了微观结构行为。在设计的样品中发现了一个间距为20μm至100μm的裂纹网络。人们注意到,可以定制微观结构的激光扫描方法会影响制造钨的裂纹行为[1]。采用不同的添加剂参数来研究微观结构性能,但发现在 AM(增材制造)中开裂实际上是不可抗拒的。由于裂纹出现在每个激光熔合路径中,然后在逐面结构过程中类似,因此可以实现裂纹链组装。
