Tóm tắt

The grain growth kinetics of commercially pure Titanium with different contents of oxygen have been studied. The 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 been calculated. Finally, tensile tests on the same materials have been carried out. When the interstitial oxygen content in titanium increases the grain growth kinetics and the ductility decrease and the α→β transition temperature, activation energy for grain growth and mechanical strength increase.
