The maximum temperature a turbine blade can withstand is a crucial indicator of turbine engine technology.
Ordinary turbine engine blades must bear temperatures above 700 degrees Celsius, and most turbine blades are made of nickel-iron alloy. The melting point of nickel-iron alloy, based on different alloy formulations, fluctuates around 950 degrees Celsius.
The standards are higher for aviation turbine engines. The higher the temperature turbine blades can withstand, the better, and the maximum thrust of the engine directly depends on this temperature.
For instance, the F119 engine of the M country's F22 fighter jet has a turbine inlet temperature of about 1700 degrees Celsius, which gives the engine a hefty thrust of 15.6 tons.
The turbine inlet temperature of Country E's AL31F engine sits around 1400 degrees Celsius, generating thrust worth 12.5 tons.
