Rhenium can increase the creep strength of nickel-high temperature alloys, which can be used to make combustion Chambers, turbine blades and exhaust nozzles for jet engines. Rhenium nickel alloy is the core material of modern jet engine blade, turbine disc and other important structural parts. The use of rhenium can improve the performance of nickel-based high temperature alloys. Alloys can also be made for single crystal blades. Both of these functions allow turbines, especially high-pressure ones, to operate at higher temperatures. In this way, the designers can increase the pressure on the turbine and improve the operating efficiency. Or the engine could speed up fuel combustion and generate more thrust. In addition, the operating temperature can be kept low and the difference between the actual operating temperature and the maximum allowable temperature of the turbine can be increased, thus extending the service life. People can also consider both aspects of the engine and improve the performance and durability of the engine.
The alloys or coating materials of rhenium and tungsten, molybdenum or platinum group metals are widely used in the electronics and aerospace industries due to their high melting point, high resistance, strong magnetism and good stability. Such as manufacturing of special incandescent light bulb shell of filament, artificial satellites and rockets, atomic reactor protection board, used as ultra high temperature heater evaporation metal, used for high temperature coating used on the rockets and missiles, spacecraft instruments and high temperature parts such as heat shield, arc discharge, electrical contactor and so on all is the use of the above characteristics of rhenium.
Rhenium can simultaneously increase the strength and plasticity of tungsten, molybdenum and chromium, a phenomenon known as the "rhenium effect". Such as adding a small amount (3% ~ 5%) of rhenium tungsten can make the recrystallization starting temperature 300 ℃ ~ 500 ℃, rhenium (Re) of the function is called the effects of rhenium. Mo-Re and W-Re alloy has good high temperature strength and plasticity, can be processed into boards, plates, wire, rod, used in aerospace, aviation high temperature structure (nozzle, nozzle, thermal protective screen, etc.), elastic components and electronic components, etc.
