Effect of melt flow on dendritic growth in AlSi7-based alloys during directional solidification

open access: yes, 2022
S.335-338High-strength automotive components are often made of AlSi7-based alloys. A very challenging problem with aluminium casting is the influence of melt flow during solidification, because it affects the microstructure formation and therefore the ...

Improved Surface Wettability of Water by Applying SiC/Ti6Al4V Coatings on Carbon/Carbon Composites

open access: yesAdvances in Materials Science and Engineering, 2013
SiC/Ti6Al4V coatings were applied on carbon/carbon composites to improve the surface wettability of water. SiC interlayers were preprepared by pack cementation to bond both the carbon/carbon composites and the Ti6Al4V, and then the Ti6Al4V coatings were ...

A mesoscale solidification simulation of fusion welding in aluminum-magnesium-silicon alloys [PDF]

open access: yes, 2014
A 3D granular model has been developed to simulate solidification during fusion welding of Al alloys. The model simulates the gradual development of the weld mushy zone composed of both continuous liquid films and solidifying grains by coupling thermal ...

Surface remelting strategy for enhancing forming quality in laser directed energy deposition of Al2O3/GdAlO3/ZrO2 eutectic ceramics: Defect suppression and microstructure evolution

open access: yesJournal of Advanced Ceramics
The intrinsic brittleness of ceramic materials and the complex temperature field used during laser directed energy deposition (LDED) inevitably lead to the formation of surface and internal defects in the fabricated components, which significantly affect
