Journal Article
Banjongprasert, C., Hogg, S. C., Liotti, E., Kirk, C. A., Thompson, S. P., Mi, J., & Grant, P. S. (2010). Spray forming of bulk ultrafine-grained Al-Fe-Cr-Ti. Metallurgical and materials transactions. A, Physical metallurgy and materials science, 41(12), 3208-3215. https://doi.org/10.1007/s11661-010-0386-0

An Al-2.7Fe-1.9Cr-1.8Ti alloy has been spray formed in bulk and the microstructure and properties compared with those of similar alloys produced by casting, powder aomization (PA), and mechanical alloying (MA) routes. In PA and MA routes, a nanoscale... Read More about Spray forming of bulk ultrafine-grained Al-Fe-Cr-Ti.

Low density Al-4Mg-1.3Li-0.4Zr and Al-6Mg-1.6Li-0.4Zr alloys were spray formed and the billets extruded under a range of conditions. The alloy compositions were selected to provide an attractive balance of tensile strength and elongation, without rel...

High-intensity ultrasound was applied during the preparation of an Al-5Ti-1B master alloy when reacting fluoride salts with molten Al. The reaction rate was significantly increased with TiB2 particles of much reduced mean diameter and narrow width sp...
