Rapid Grain Growth of Commercial Purity Titanium.
Abstract
Large-grain specimens of commercial purity titanium (A40) were produced in a short time. It was observed that transformation strains can cause rapid grain growth of pure titanium, and that a temperature gradient (100 F/in (approx. 2 C/mm) ) formed in a furnace may enhance the grain growth. Transformation strains were obtained by air-cooling through the beta transus (1620 F (882 C) ). A brief discussion of the mechanism of rapid grain growth in commercial purity titanium is given in connection with the beta to alpha transformation, which occurs at 1620 F (882 C) on cooling.
