Fundamental Studies of the Microstructures of Rapidly Solidified Ti3Al+Zr and Ti3Al+Nb
The microstructures of Ti3Al+lZr (α2Zr) and Ti3Al+Nb (α2+Nb) produced by ingot metallurgy (IM) and by rapid solidification (RS) are compared. Grain refinement was observed in both RS Ti3Al+Zr and RS Ti3Al+Nb alloys, and heat treatment of RS Ti3Al+Nb ribbons produced refined α2 microstructures compared with those observed in the IM material. Ti3Al+Nb RS ribbons yielded good room temperature tensile strenth and elongation, and were successfully compacted by extrusion at 925°C (1700°F), resulting in a fine α2 structure.
