Embodiment

[0023] Embodiment: The composition of the alloy material is less, and the change in content is small. The present invention is only described in detail through this example. It has been verified that the influence of composition change and temperature change on the performance of the guide rod can be ignored compared with the existing guide rod.

[0024] A high-purity molybdenum-rhenium-lanthanum ternary alloy guide rod. The alloy material for preparing the guide rod includes the following components in parts by weight: 1-2 parts of rhenium, 1-2 parts of lanthanum, and 90-100 parts of molybdenum.

[0025] The production process of the high-purity molybdenum-rhenium-lanthanum ternary alloy guide rod comprises the following steps:

[0026] (1) Preparation of molybdenum powder: Roast ammonium molybdate as a molybdenum source to obtain molybdenum trioxide, then perform a reduction reaction to reduce molybdenum trioxide to molybdenum dioxide, and then perform a second reduction reac...

Abstract

The invention discloses a high-purity molybdenum rhenium lanthanum ternary alloy guide rod, and belongs to the field of an alloy material. The alloy material for preparing the guide rod comprises, byweight part, 1 to 2 parts of rhenium, 1 to 2 parts of lanthanum, and 90 to 100 parts of molybdenum. The purity of the molybdenum is higher than 99.99%. The molybdenum rhenium lanthanum alloy is subjected to ternary alloying, the material comprises , 1 to 2 parts of rhenium, 1 to 2 parts of lanthanum and the balance molybdenum, the alloy property is greatly improved, meanwhile, the adding amount ofheavy metal rhenium and rare earth lanthanum can be strictly controlled, the production cost of the alloy is reasonably controlled, the number of eddy current inspection crack points of the microwavefurnace magnetic control guide rod made of the alloy is greatly smaller than that of the similar product, the strength range is smaller than that of the similar product, the service life is prolonged, and the product yield is improved.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a production process applied to a guide rod required by a microwave oven magnetron coil. Background technique [0002] Molybdenum-rhenium-lanthanum alloy can improve the plasticity of molybdenum, increase the strength of molybdenum and improve the high temperature creep performance. Generally, molybdenum-rhenium alloys are divided into low-rhenium (2%-5%) molybdenum alloys and high-rhenium (11%-50%) molybdenum alloys according to the rhenium content. CN106756157A discloses a method for preparing a molybdenum-rhenium-lanthanum alloy material, and in the molybdenum-rhenium-lanthanum alloy material, it is mentioned that rhenium is 1.0%-5.0%, lanthanum is 0.02%-2%, and the balance is molybdenum , the rhenium content also belongs to the low rhenium range. Low-rhenium-molybdenum alloys are considered to have little advantage in strengthening the molybdenum matrix. [0003] At present,...
