Explanation: the addition of rhenium can greatly improve the strength and plasticity of tungsten, molybdenum and chromium, people call this phenomenon "rhenium effect". A small amount of rhenium (3% ~ 5%) can raise the initial recrystallization temperature of tungsten by 300℃ ~ 500℃. Tungsten-rhenium and molybdenum-rhenium alloy have good high temperature strength and plasticity, can be processed into plate, sheet, wire, wire, rod, used in aerospace high temperature structural parts (nozzle, nozzle, heat shield, etc.), elastic elements, electronic elements, etc., can also be used in the manufacture of heating elements, workpiece, bulb, X-ray equipment and medical equipment. W-re-tho2 alloy can be used as high temperature heating workpiece, tungsten-rhenium, molybdenum-rhenium alloy contacts have high thermal corrosion resistance and high temperature conductivity, can improve the service life and work reliability of power supply equipment. Such as: platinum rhenium alloy; Platinum-tungsten-rhenium alloy; Tungsten-rhenium alloy; Molybdenum rhenium alloy and so on.
Rhenium is very expensive, and rhenium alloys are mostly used in its application, among which tungsten-rhenium and molybdenum-rhenium alloys are the most widely used. The rhenium content of tungsten rhenium alloy is 1% ~ 26%, and that of molybdenum rhenium alloy is 11% ~ 50%. In addition, there are w-33.3 mo-33.3 Re, mo-re-hf-zr, mo-re-hf-v alloy, tungsten and nickel-based plus rhenium diversified super-heat resistant alloy, etc. The latter several alloys have high strength and high temperature performance, and are used in key components of aerospace equipment.
Main brands of alloy: re8-12 -- Ni -- Cr, Re30 -- W -- Mo30, mo-re-hf -- V, mo-re-hf -- Zr, w-2.6 re-1tho2 alloy, etc
