Behaviour of normal grain growth kinetics in single phase titanium and titanium alloys

Abstract The grain growth kinetics of commercially pure Titanium, Ti–0.2Pd in the α and β phases, Ti–6Al–4V and Ni–Ti in the β phase have been studied. The perimeter, diameter and area as grain size parameters have been measured by means of the image analysis technique for different heat treatment temperatures and times. The growth exponents and activation energies have also been determined. The influence of the grain size on the mechanical properties have been evaluated and for the Ni–Ti shape memory alloy, the influence of the grain growth on the transformation temperatures, thermodynamic magnitudes and on the transformation stresses has been determined.
