High-Performance Tungsten Rhenium Alloy Innovation Projects

High-performance tungsten rhenium alloy production must first address the element rhenium alloy homogeneous distribution, which is the production of tungsten rhenium alloy wire preparation of the core technology ; swaged , annealing and drawing process parameters and process selection is tungsten- rhenium alloy wire thermal deformation processing of key technologies.

The Innovation of This Project Is To :

A ) the introduction of the food industry used in the medical use of horizontal mixing pot doping , the use of two solid-liquid doping process , to ensure the amount of rhenium and homogeneous distribution of elements are added at the same time , ensure that potassium alloy , aluminum, sulfur content in a certain range .

2 ) tungsten- rhenium alloys with rhenium solid solution strengthening effect now , alloy hardening speed, using a small compression ratio , the corresponding annealing point selection , the successful introduction of
3.7mm tungsten rod to protect high hydrogen annealing process and protection of the filament is energized hydrogen annealing solution annealing process of oxidation caused by burning and tungsten- rhenium combustion phenomenon.

Doping the second liquid , a liquid doping - pickling process , to ensure potassium alloys , aluminum and sulfur contents of the required range of the alloy ; medical food into the pot as a dopant doped with horizontal , 30kg pickling tungsten powder and the amount of ammonium perrhenate solution was stirred until dry, combination through this process to ensure that the ammonium perrhenate crystals wrapped in each uniform surface tungsten particles precipitated , makes the material in the hydrogen reduction process occurs pre-alloyed for homogeneous distribution of rhenium tungsten rhenium alloy wire to provide an initial ingredients guaranteed.

Tungsten- rhenium alloys with rhenium solid solution strengthening effect now , alloy hardening speed, using a small compression ratio , the corresponding annealing point selection , the successful introduction of hydrogen tungsten rod 3.7mm induction annealing process and the protection of the filament is energized hydrogen annealing protection solution cause oxidation during annealing and tungsten- rhenium burning combustion phenomenon, determined from the whole of 17mm ~ 2mg/200mm tungsten thermal deformation process , a small compression ratio and 7 times the annealing process combination processing to the diameter 0.39mm tungsten single weight of not less than 2.8kg, has reached the international advanced level.
