Effect of powder variability on laser powder bed fusion processing and properties of 316L

چکیده
To date, the effects of powder properties, both physical and chemical, on printed properties as-built components is still a topic that poorly understood. A contributing factor lack relevant methods for evaluating rheological powder, or flowability. This study presents review different 316 L grades were produced using various atomization techniques. The evaluated metallurgical techniques, rheometer (FT4) rotating drum analyser (RPA). results indicate FT4 RPA are suitable characterization. However, parameter selection evaluation must be done keeping in mind application, this case thin layer spreading. It was found all bulk density measurements, basic flow energy break able to differentiate between predict how will laser-based powder-bed fusion process. Despite some printability challenges water atomized at higher thicknesses, it gas performed similarly despite minor differences particle size distribution. Furthermore, variability did not show any detrimental resulting mechanical properties.

Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. This thesis is about some aspects of when and how to Design for Additive Manufacturing (DfAM) when using the PBF method i...
متن کاملStudy of the Microstructure and Cracking Mechanisms of Hastelloy X Produced by Laser Powder Bed Fusion
Hastelloy X (HX) is a Ni-based superalloy which suffers from high crack susceptibility during the laser powder bed fusion (LPBF) process. In this work, the microstructure of as-built HX samples was rigorously investigated to understand the main mechanisms leading to crack formation. The microstructural features of as-built HX samples consisted of very fine dendrite architectures with dimensions...
