Mechanisms and Kinetics of Static Spheroidization of Hot-Worked Ti-6Al-2Sn-4Zr-2Mo-0.1Si with a Lamellar Microstructure

The effect of imposed strain ε, annealing temperature T A, and annealing time τ on the static spheroidization behavior of Ti-6Al-2Sn-4Zr-2Mo-0.1Si having an initial lamellar microstructure was investigated. For this purpose, the samples were compressed isothermally at 1173 K (900 °C) to ε = 1.0 and subsequently annealed at 1228 K (955 °C) ≤ T A ≤ 1253 K (980 °C) for 10 minutes ≤ τ ≤ 24 hours. For each test condition, metallography was performed...
