1. Introduction to TC4 Materials<\/span><\/strong>
\nTitanium alloy TC4 is a typical (\u03b1+\u03b2) type titanium alloy. The corresponding grade of TC4 is Ti-6Al-4V. Since it contains 6% of the \u03b1-stabilizing element Al and 4% of the \u03b2-stabilizing element V, TC4 has good comprehensive performance. It also has the advantages of low density, high specific strength, good corrosion resistance and good process performance. It is an ideal aerospace engineering structural material with a high specific strength.<\/span><\/p>\n

Titanium alloy TC4 can be used in 400\u2103 for a long time. It is mainly used in the aviation industry to manufacture fans and compressor discs for engines, as well as important structural parts such as beams, joints and partitions in aircraft structures. TC4 is mainly used in annealed state, and can also be further used to make solution failure treatment. It has good process plasticity and superplasticity, and is suitable for various pressure processing and molding. Welding and machining can also be carried out in various ways.<\/span><\/p>\n

\nAMST\/B265 ASTM\/B265 titanium and titanium alloy tapes and foils<\/span><\/p>\n

TC4 heat treatment performance<\/span><\/strong>
\nTC4 titanium alloy heats to 1020 degrees, and the high-temperature microstructure of the alloy is composed of single-phase \u03b2, which is a solid solution. When the microstructures obtained are different at different cooling rates, such as water quenching, air cooling and furnace cooling, the microstructure obtained is different. The water quenching (WQ) structure is martensite \u03b1’+\u03b2 phase, the air cooling (AC) structure is needle-shaped \u03b1+\u03b2 phase and original \u03b2 grain boundary phase, and the furnace cooling (FC) structure is strip-shaped \u03b1+\u03b2 phase and original \u03b2 phase grain boundary.<\/span><\/p>\n

As in the above case, when heated to 950 degrees and 850 degrees, the microstructure obtained after cooling is also different after different cooling speeds. At 950 degrees, the quenched (WQ) tissue in water is the primary equiaxed \u03b1 phase and \u03b1’+\u03b2 phase, the air-cooled (AC) tissue is the primary equiaxed \u03b1 phase and the needle-shaped \u03b2 phase, and the furnace-cooled (FC) tissue is the primary equiaxed \u03b1 phase and the grain boundary. At 850 degrees, the quenched (WQ) tissue in water is the primary equiaxed \u03b1 phase and the metastable \u03b2 phase, and the air-cooled (AC) tissue is the primary equiaxed \u03b1 phase and the transformed \u03b2 phase.<\/span><\/p>\n

After heating to 1020 degrees, 950 degrees and 850 degrees, it cools at different cooling speeds. The room temperature mechanical properties are shown in Table 1<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n
