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 Fin approx. 2 Cmm 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. Author
