How does the single track width and depth vary with different powder feed rates and scan speeds?
Best insight from top research papers
The single track width and depth in laser powder bed fusion processes vary significantly with different powder feed rates and scan speeds. Studies have shown that the width and depth of the melt pool decrease at higher scan speeds, while they increase with an increase in laser power . Additionally, the width and depth of the melt pool are influenced by the laser scan speed, with higher speeds resulting in reduced dimensions. Furthermore, the scanning speed affects the track profile, determining the step between tracks for uniform coverage. These findings highlight the intricate relationship between powder feed rates, scan speeds, and the resulting dimensions of the single tracks in laser powder bed fusion processes.

How does the porosity of a soil change with depth?5 answersThe porosity of soil changes with depth. In general, the porosity decreases with increasing depth. This is supported by several studies. The variation in porosity with depth is influenced by factors such as tillage practices and soil texture. For example, conventional tillage (CT) systems tend to have higher porosity compared to no-tillage (NT) systems. The distribution of pore sizes also changes with depth, with different tillage systems resulting in different pore size distributions. Additionally, the shape and connectivity of pores can vary with depth. Overall, the porosity of soil decreases with depth, and this variation is influenced by factors such as tillage practices and soil texture.
What is the relationship between powder feed rate and solidification cracks?5 answersThe relationship between powder feed rate and solidification cracks is influenced by various factors. In the study by Choi et al., cracks were observed at high powder feeding rates during laser surface-melting alloying process. Similarly, Alizadeh-Sh et al. found that solidification cracking occurred during laser cladding of Inconel 718 powder on A-286 iron based superalloy. On the other hand, Caton et al. investigated the effect of solidification rate on small-crack growth behavior in a 319-type aluminum alloy and found that faster solidification rates resulted in slower growth rates of small cracks. Additionally, Zhang et al. reviewed the issue of solidification cracks in LPBF manufactured aluminum alloys and discussed methodologies for crack inhibition, including optimization of process parameters. Therefore, the relationship between powder feed rate and solidification cracks is complex and depends on the specific alloy and processing conditions.
How does the grain size of 316L change along the depth of a laser powder bed fusion (LPBF) part?5 answersThe grain size of 316L stainless steel in laser powder bed fusion (LPBF) parts changes along the depth. In one study, columnar grains were observed growing along the build direction, and with increasing laser power, the columnar grains became coarser and higher in proportion. Another study found that the incorporation and uniform distribution of Al2O3 nanoparticles in the LPBF process resulted in a considerable grain structural refinement down to the nanometric scale. Additionally, electron backscatter diffraction analysis revealed columnar grains in LPBF parts. These findings suggest that the grain size of 316L stainless steel in LPBF parts can vary depending on factors such as laser power and the presence of nanoparticles.
What are the description of single dose vials?5 answersSingle-dose vials are designed to be used in conjunction with a medication regimen. They typically include a removable member that prevents the liquid solution from escaping, but allows for easy administration of the solution. These vials can contain one or more discrete capsules with the same or different liquid solutions. Multiple capsules can be arranged within a vial so that different solutions are ejected simultaneously or sequentially when pressure is applied to the capsules. Additionally, single-dose vials can be connected to one another in a strip configuration, making it easier for individuals to adhere to a medication regimen that requires multiple doses over time.
What is the effect of strain rate on soil behavior?5 answersThe effect of strain rate on soil behavior has been studied in several papers. It has been found that the loading rate heavily influences the excess pore water pressure (EPWP) and soil strength. In triaxial extension stress path tests, it was observed that the EPWP tends to be negative at small axial strain and then increases to be positive with the increase of axial strain. The normalized deviatoric stress versus loading rate curves follow a backbone curve, and the minimum deviatoric strength occurs at a normalized loading rate of Vref=5. The strain rate also affects the friction angle and dilation angle of dry cohesionless sands, with shear strength increasing up to a certain level and then decreasing as the shearing rate increases. These findings have implications for the design of geotechnical structures and can help improve their performance in practice.
