Product Description

Molybdenum-Rhenium Alloy Sheet


1. Description of Molybdenum Rhenium Alloy Sheet:


Molybdenum-rhenium alloy sheet is an alloy made of rhenium as the alloying element and molybdenum as the matrix element. The alloy has a rhenium effect that increases plasticity, and it typically contains 11% to 50% rhenium (mass fraction).


In addition to having great thermal, electrical, and corrosion resistance, the refractory metal molybdenum also has a low thermal expansion coefficient, high hardness, and strong high temperature strength. so molybdenum has a wide range of applications in the electronics industry, aerospace industry, energy industry and other fields the use of. However, the application of pure metal molybdenum is restricted due to its somewhat brittle nature at room temperature, poor processability, poor weldability, ease of oxidation, and recrystallization brittleness. Adding a certain amount of alloying elements such as Re element is an effective method to improve the brittleness of metal molybdenum. The performance of molybdenum at high temperatures can also be improved by adding rhenium, in addition to its performance at normal temperatures and during welding.

3. Classification of Preparation Methods of Molybdenum-Rhenium Alloy Sheet:


Molybdenum Rhenium Alloy Sheet


- Powder metallurgy

- Medium temperature sintering

-Vacuum melting method


Powder metallurgy:First, the molybdenum powder and the rhenium powder are mixed uniformly, and then molded or isostatically pressed, and then a molybdenum-rhenium alloy with a relative density of about 90% can be produced through pre-bonding and high-temperature sintering at a temperature of more than 2000 °C. The purity of molybdenum powder used in the preparation of molybdenum-rhenium alloy is generally greater than or equal to 99.95%, and the purity of rhenium powder is generally greater than or equal to 99.98%, and the average particle size of these two powders is generally less than 5μm.


Medium temperature sintering:Compared with the above method, the difference between medium temperature sintering is that the raw materials used are different. The materials used are MO3 and NH4ReO4. After mixing, molybdenum-rhenium alloy powder is prepared by co-reduction, and then pressed, pre-bonded and sintered at 1700 °C at medium temperature. A molybdenum-rhenium alloy ingot is prepared. The preparation of molybdenum-rhenium alloy by powder metallurgy method is simple and low in cost, but the impurity content of the ingot is often high. When the rhenium content is high, the alloy ingot is also prone to form a brittle σ phase.


Vacuum melting method:In order to overcome the above shortcomings, vacuum smelting and purification technology was applied to the preparation of molybdenum-rhenium alloy. In comparison, the molybdenum-rhenium alloy ingot prepared by vacuum smelting has low impurity content, especially the reduction of gas elements is very obvious, and the second phase is not It is easy to precipitate, which is beneficial to the subsequent processing of molybdenum-rhenium alloy; however, the grains of molybdenum-rhenium alloy ingots prepared by this method are usually very coarse, which is not conducive to the opening of the alloy. The plastic-brittle transition temperature of pure molybdenum is near normal temperature, so it is impossible to plastically process molybdenum ingots at normal temperature. The addition of rhenium greatly reduces the plastic-brittle transition temperature of molybdenum alloy, which makes molybdenum show good workability at room temperature.


4. Application of Preparation Methods of Molybdenum-Rhenium Alloy Sheet:


Molybdenum-rhenium alloy sheet can be used as high-speed rotating X-ray tube target, long-life grid plate for microwave communication, space reactor core heating tube, high-temperature furnace heating element, high-temperature thermocouple, etc. The room temperature tensile strength ductility resistivity of molybdenum-rhenium alloy increases with the increase of rhenium content. Mo-41% and 5%Re Re is typically utilized as a thermocouple wire for aerospace structural materials.Mo-50%Re as high temperature structural material.
