| Abstract Scope |
For high temperature applications, the Al-Fe-V-Si system has been of particular interest due to the formation of coarsening resistant and thermally stable α-Al(Fe,V)Si phase during rapid solidification. Several commercial alloys were developed, but are in limited use due to the difficulty and expense of processing. However, cooling rates in the laser powder bed fusion process approach those of traditional rapid solidification techniques, allowing for the possibility of revisiting rapid solidification systems. This study re-examines the Al-Fe-V-Si system for use in laser powder bed fusion. Initial parameter development was conducted and high density processing windows were found with no solidification cracking. Tensile and fatigue specimens were produced and tested for a preliminary evaluation. Additionally, the microstructure was investigated using transmission electron microscopy to compare to traditional rapidly solidified microstructures. |
