Notes:
This work presents an investigation of the spray forming and downstream processing ofAl alloys that are difficult to produce in bulk by conventional solidification processing: Al-Fe-Cr-Tialloys for intermediate temperature applications and Al-Si-Li alloys for high stiffness, low densityapplications in fast moving machinery. For the Al-Fe-Cr-Ti alloys, spray forming is beinginvestigated to allow the scale-up of alloy compositions previously explored only as ribbons orpowders in traditional rapid solidification routes. For Al-Si-Li alloys, spray forming is used toprovide globular primary AlLiSi in a fully divorced AlLiSi/α-Al eutectic structure. For both alloys,the as spray formed and downstream processed microstructure of 20kg billets has been investigatedby scanning electron microscopy, electron probe microanalysis, and X-ray diffractometry.Preliminary mechanical properties have also been investigated
