Zirconia Ceramics:

Zirconia In the 1970s, the amount of titanium alloy used in aeroengines generally accounted for 20% to 30% of the total weight of the structure. It was mainly used to manufacture compressor components, such as forged titanium fans, compressor discs and blades, and cast titanium compressors. Cassettes, intermediate casings, bearing housings, etc. The spacecraft mainly uses the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, frames and rocket shells. Artificial earth satellites, lunar modules, manned spacecraft and space shuttles also use titanium alloy sheet welded parts. Commonly used heat treatment methods are annealing, solid solution and aging treatment. Annealing is to eliminate internal stress, improve plasticity and structural stability, and obtain better overall performance. Generally, the annealing temperature of α alloy and (α+β) alloy is selected at 120～200℃ below the (α+β)─→β phase transformation point; the solution and aging treatment are rapid cooling from the high temperature zone to obtain martensite α′ Phase and meta-stable β-phase, and then heat preservation in the middle temperature zone to decompose these meta-stable phases to obtain α-phase or compound and other finely dispersed second-phase particles to achieve the purpose of strengthening the alloy. Usually (α+β) alloys are quenched at 40～100℃ below the (α+β)─→β phase transition point, and metastable β alloys are quenched at 40～80℃ above the (α+β)─→β phase transition point. conduct. The aging treatment temperature is generally 450 to 550°C.
