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

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

Come nel caso precedente, quando si riscalda a 950 gradi e a 850 gradi, anche la microstruttura ottenuta dopo il raffreddamento \u00e8 diversa a seconda della velocit\u00e0 di raffreddamento. A 950 gradi, il tessuto quenched (WQ) in acqua \u00e8 costituito dalla fase primaria equiaxed \u03b1 e dalla fase \u03b1'+\u03b2, il tessuto raffreddato ad aria (AC) \u00e8 costituito dalla fase primaria equiaxed \u03b1 e dalla fase \u03b2 aghiforme e il tessuto raffreddato in forno (FC) \u00e8 costituito dalla fase primaria equiaxed \u03b1 e dal limite del grano. A 850 gradi, il tessuto quenched (WQ) in acqua \u00e8 costituito dalla fase \u03b1 equiaxed primaria e dalla fase \u03b2 metastabile, mentre il tessuto raffreddato ad aria (AC) \u00e8 costituito dalla fase \u03b1 equiaxed primaria e dalla fase \u03b2 trasformata.<\/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
