Spattering at a melt pool or denudation of powder near the laser movement may affect the smooth functioning of the process. In addition, several other complicated, stochastic occurrences and interlink phenomena may not be understood or identified. A large number of complications make the LPBF ...
A gaseous elemental mercury (Hg0) sampler was developed for the assessment of mercury (Hg) pollution from the air and utilised aluminium (Al) powder as the accumulation medium. The Hg sampler is presented as an alternative cost-effective sorbent that can be used for the assessment of Hg pollu...
In this paper, a phenomenological model to predict the value of the electrical resistance of a compressed metal powder mass is proposed. The model, based on the experimental compressibility and resistivity-porosity curves, is useful in the field of the electrical resistance consolidation. In this ar...
Based on a study of the mechanical properties of bridge deck leveling concrete (BDLC) containing different mud powders at various ages, the effects of mud powders on concrete durability were evaluated through rapid chloride permeability testing, freeze–thaw testing, and the coupling of salt ...
HPMCAS LG is a mixture of acetic acid and monosuccinic acid esters of HPMC in granular form, often used as an enteric coating due to its pH-sensitive character (soluble at pH > 5.5) and rapid dissolution in the upper intestine. It is also useful in the formulation of ASDs. HPMCAS LG ...
This study investigates the effect of support structures on the properties of Inconel 718 (i.e., IN718) parts produced by the laser powder bed fusion (LPBF) additive manufacturing process. Specifically, the effects of support structure shape (i.e., pin-t
Concerning the distribution of temperatures (refer to Figure 4b), in this specific simulation configuration, it was observed that the peak temperatures were concentrated near the heat source, situated between the supporting structures and the overhang surface of the component. It can also be observed...
Metal matrix self-lubricating composites exhibit outstanding performance in various environments, reaching the required properties by modifying the reinforcement–matrix ratio and the production method. The present research investigated the effects on tr
A model extension will be sought in the near future to account for all such effects, following approaches similar to Ariane et al. [16] and Schulz et al. [20]. In order for complete carrier deaggregation, other mechanisms should be incorporated, such as subsequent impacts or fluid dynamics...
