Heat Treament

The world's first successfully developed high-temperature titanium alloy is Ti-6Al-4V, with a service temperature of 300-350 °C. Subsequently, alloys such as IMI550 and BT3-1 with a service temperature of 400°C, and alloys such as IMI679, IMI685, Ti-6246, and Ti-6242 with a service temperature of 450-500°C were successively developed. New high-temperature titanium alloys that have been successfully used in military and civil aircraft engines include IMI829 and IMI834 alloys in the UK; Ti-1100 alloys in the United States; BT18Y and BT36 alloys in Russia. Table 7 shows the maximum service temperature of new high-temperature titanium alloys in some countries [26].

The β-type titanium alloy was originally the B120VCA alloy (Ti-13v-11Cr-3Al) developed by the American Crucible Company in the mid-1950s. β-type titanium alloy has good cold and hot processing performance, easy forging, rolling and welding, and can obtain high mechanical properties, good environmental resistance and good cooperation between strength and fracture toughness through solution-aging treatment. The most representative types of new high-strength and high-toughness β-type titanium alloys are as follows [26,30]:
Ti1023 (Ti-10v-2Fe-#al), the alloy is equivalent to the 30CrMnSiA high-strength structural steel commonly used in aircraft structural parts, and has excellent forging performance;
Ti153 (Ti-15V-3Cr-3Al-3Sn), the cold workability of this alloy is better than industrial pure titanium, and the room temperature tensile strength after aging can reach more than 1000MPa;
β21S (Ti-15Mo-3Al-2.7Nb-0.2Si), this alloy is a new type of anti-oxidation, ultra-high-strength titanium alloy developed by the Timet Division of the American Titanium Metal Corporation. It has good oxidation resistance and cold and hot processing properties Excellent, can be made into foil with a thickness of 0.064mm
