The kinetics of beta grain growth during short-time, supertransus heat
treatment of Ti-6Al-4V were determined using a salt-pot technique. Th
e finite-time, subtransus temperature transient during salt-pot heatin
g was quantified through measurements of the heat transfer coefficient
characterizing conduction across the salt-titanium interface and a si
mple heat conduction analysis which incorporated temperature transient
were successfully fit to the parabolic grain growth law d(n) - d(0)(n
) = kt exp(-Q/RT) using an exponent n equal to 2.0. Comparison of the
present results to rapid, continuous heat treatment data in the litera
ture for a similar titanium alloy revealed a number of semi-quantitati
ve similarities.
