摘要：
In this study, fully dense tungsten samples were additively manufactured and the micro-structure behavior was studied. A crack network with a spacing of 20 mu m up to 100 mu m 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.
