The titanium-rich side phase diagram of the Ti-Al system has been re-examined. Electrical resistance measurements, X-ray analysis and microscopic observations were carried out to determine the equilibrium relations among the inter-solid phases. A partial phase diagram up to 50% Al by weight was constructed as shown in Fig. 16. The Al-saturated α-Ti solid solution exists conjugately with the α₂ phase for the temperature range below 1020°C, at which temperature a peritectoid reaction, β-Ti+α₂\ ightleftharpoonsα-Ti, takes place. The α₂ phase exists in the range from 19 to 25% Al by weight and it corresponds to Ti₂Al. One new phase named δ has been assumed to exist in the composition range from 26 to 34% Al by weight at high temperatures.<BR>The non-variant reactions in the solid alloys of this system were determined as follows;<BR>(Remark: Graphics omitted.)
