High Temperature Stability of an Al–Zr–Ti Alloy Prepared using Gas Atomization and Spark Plasma Sintering Technology
Original language description
The aim of this study was to prepare an aluminium alloy with high temperature stability using the powder metallurgical route. Gas atomized powder of the Al–Zr–Ti alloy was consolidated by the spark plasma sintering (SPS) technology. The fine grained structure (grain size between 2 and 3 µm) observed in the gas atomized powder was retained after sintering both at 425◦C and 550◦C. The microhardness of 49 HV observed in the gas atomized powder was increased up to about 100 HV in the SPS compacts. Precipitation of the Al3(Zr,Ti) phase during sintering can explain this strengthening. The materials stability was tested by annealing at temperatures above 450◦C. The grain size remained stable even after 10 h of annealing. A decrease in microhardness by about 20% can be attributed especially to the formation of the stable modification of the Al3(Zr,Ti) phase.
