Controlled Expansion Alloy Factories

Controlled Expansion Alloy Factories

The expansion alloy usually contains more than a dozen elements, and the composition is very complex. The alloying elements improve the thermal strength and thermal stability through solid solution strengthening, second phase strengthening and grain boundary strengthening respectively. By adding chromium, cobalt, tungsten, and molybdenum Equal high melting point elements form solid solution and play a role in solid solution strengthening. Expanded alloys are used to manufacture important parts such as combustion chambers, tail nozzles and some turbine disks, high-pressure compressor disks, etc., but in the two most important positions of gas turbine engines, the turbine guides Deformed superalloys have been replaced by expanded alloys on blades and rotor blades, starting to give way to powdered superalloys on turbine disks.
