Explanation

Titanium alloys designed for long-term use in high-temperature environments. It has high instantaneous and endurance strength, good creep resistance and good thermal stability in the operating temperature range. The main type of martensite capable of long-term operation below 5O0 ° C is high aluminum equivalent α-β Type heat resistant titanium alloy. They all contain a lot of dumplings α Stable elements with aluminum equivalent above 6%, strengthened through solid solution α The corresponding high temperature endurance and creep strength of phase were obtained; Add appropriate β Stabilizing elements (such as molybdenum) improve instantaneous strength and thermal stability. The aluminum equivalent of all heat resistant titanium alloy is generally less than 8% to ensure excellent thermal stability, which is mainly used to manufacture disks, blades, guides, spacers, inlet casings and other parts in compressors.
