Abstract

Aging works of two melt-spun Al-2 at pct (Ti,V,Zr) alloys showed that metastable L12 Al3(Ti,V,Zr) precipitates were dominant and did not transform to stable D023 ones: the average radius was 3 to 4 nm and the interparticle spacing was 10 to 30 nm at 698 K up to 400 hours. Coarsening kinetics was found to be very sluggish and was coincident with the low lattice mismatch. Due to the low coarsening rate and the high thermal stability of the precipitated phase, rapidly so-lidified Al-Ti-V-Zr systems show promise as base of high-strength Al alloys for high-temperature applications.
