Embodiment Construction

[0020] The features and advantages of the present invention will be described in detail below by means of embodiments, but the present invention is not limited thereto.

[0021] Three batches of molybdenum-rhenium alloy plates and foils with different rhenium contents have been prepared by the above method. Table 1 shows the specific preparation process steps and process parameters of the three batches of molybdenum-rhenium alloy foils. Table 2 shows the correlation of the obtained three batches of alloy materials. performance data. Among them, the rhenium content in the first batch of molybdenum-rhenium alloy materials is 5wt%, the rhenium content in the second batch of molybdenum-rhenium alloy materials is 35wt%, and the rhenium content in the third batch of molybdenum-rhenium alloy materials is 50wt%.

[0022] In a nutshell, the preparation methods of the above three batches of molybdenum-rhenium alloy plates and foils are as follows:

[0023] 1) According to the distribut...

Abstract

The invention discloses a method for preparing a molybdenum-rhenium alloy foil, and particularly relates to a technology for preparing the foil with thickness less than 0.1mm. The method comprises the following steps of preparing molybdenum-rhenium alloy powder; mould-pressing the molybdenum-rhenium alloy powder so as to obtain a pressed shape; sintering the pressed shape so as to obtain a sintered base; sequentially carrying out hot rolling, warm rolling and cold rolling on the sintered base so as to obtain the molybdenum-rhenium alloy foil with required thickness. The method is applicable to industrial mass production, has high production efficiency, and can also be used for preparing different thicknesses of molybdenum-rhenium sheets according to market requirement.

Description

technical field [0001] The invention belongs to the field of powder metallurgy preparation, in particular to a preparation method of high-molybdenum-rhenium alloy foil. Background technique [0002] Molybdenum not only has excellent thermal conductivity, electrical conductivity, corrosion resistance, low expansion coefficient, low vapor pressure and other properties, but also has high hardness and high strength properties. Therefore, molybdenum has a very broad application in the fields of electronics industry and glass manufacturing industry. However, the plastic-brittle transition of molybdenum is a very important factor affecting its application. Adding rhenium to molybdenum can improve the plasticity of molybdenum, and at the same time increase the strength of molybdenum, and greatly reduce the plastic-brittle transition temperature, so that the Mo-Re alloy has good low-temperature performance; at the same time, rhenium can improve the molybdenum alloy. The recrystalli...
