The application of heat treatment of annealing in cold worked metallic materials can result in phenomena of recovery, recrystallization and grain growth. Such heat treatment results in the transformation of the microstructure and, therefore, of the physical and mechanical properties of the material. The objective of this work is to determinate the characteristics parameters of the process of recrystallization and grain growth of Commercially Pure Titanium (cp-Ti), through the development and application of a theoretical model based on the Cellular Automata algorithm. This theoretical model will consider the reduction of interfacial energy on the grains boundaries in each time step as driving force of the process, as well as the influence of a potential barrier.
