Abstract

Hot compression tests of the as-forged Ti-alloy TB6 were conducted by means of thermecmaster-Z hot simulation test machine in temperature range of 950~1100^oC with strain rate of 0.001~1 s^-1 aiming to reveal its characters of hot compressive deformation behavior and dynamic recrystallization (DRX). Results show that the deformation activation energy of the alloy in the beta phase region is 246.7 kJ/mol; the deformation mechanism of this alloy in hot deformation is dominated by DRX, and the predominant nucleation mechanism for the growth of new grains of DRX may be ascribed to bulging nucleation. Completely dynamic recrystallization can be reached at strain rate of 0.01~0.1 s^-1 and temperature below 1000^oC, resulting in grain refinement of deformed microstructure. DRX grain coarsening was observed for the alloy deformed at temperatures above 1000^oC and strain rates below 0.001 s^-1. DRX grain size relate to Z parameter, which can be described by a function of D=6.44×10²·Z ^-0.1628.
