Embodiment 1
[0023] A method for manufacturing a resonant rod, the flow chart of which is as follows figure 1 shown, including:
[0024] Step S1, uniformly mechanically mixing 88%-98% iron-nickel alloy powder, 1%-8% carbonyl iron powder and 1%-8% carbonyl nickel powder by weight.
[0025] In the embodiment of the present invention, the weight ratio of the iron-nickel alloy powder is preferably 92-96%, the weight ratio of the carbonyl iron powder is preferably 2-4%, and the weight ratio of the carbonyl nickel powder is preferably 2-4%. Most preferably, the weight ratio of the iron-nickel alloy powder is 94%, the weight ratio of the carbonyl iron powder is 3%, and the weight ratio of the carbonyl nickel powder is 3%. It should be noted that the raw materials inevitably contain a small proportion of impurities such as carbon, nitrogen, sulfur and phosphorus, and generally the proportion of impurities is not more than 0.1%.
[0026] In the embodiment of the present invention, the iron-nickel...
Embodiment 2
[0048] A kind of resonant bar 10, its structural schematic diagram is as figure 2 As shown, the height of the resonant rod is H, and the outer diameter is D. The resonant rod 10 includes iron-nickel alloy with a weight ratio of 88%-98%, carbonyl iron with a weight ratio of 1%-8%, and carbonyl nickel with a weight ratio of 1%-8%, and the iron-nickel alloy, carbonyl iron and Nickel carbonyl is pressed or injection molded into resonant rods.
[0049] Using the iron-nickel alloy, carbonyl iron and carbonyl nickel in the above ratio, the resonant rod is made by one-time molding process, which greatly reduces the loss of raw materials and saves the cost of machining
[0050] In the embodiment of the present invention, the weight ratio of iron-nickel alloy is preferably 92-96%, the weight ratio of iron carbonyl is preferably 2-4%, and the weight ratio of nickel carbonyl is preferably 2-4%. Most preferably, the weight ratio of iron-nickel alloy is 94%, the weight ratio of iron carb...
Embodiment 3
[0055] A resonant rod, which contains iron-nickel alloy with a weight ratio of 88%-98%, carbonyl iron with a weight ratio of 1%-8%, and carbonyl nickel with a weight ratio of 1%-8%, and the iron-nickel alloy, carbonyl iron It is uniformly mixed with nickel carbonyl in powder form and formed into a resonant rod.
[0056] In the embodiment of the present invention, the high-performance iron-nickel alloy microwave resonator rod is prepared by using uniformly mixed powder with iron-nickel alloy powder as the main body to form a resonator rod, which can minimize the segregation of alloy components and eliminate coarse and uneven Microstructural defects, thereby improving the performance index and stability of the corresponding products.
[0057] In a further embodiment of the present invention, the weight ratio of iron-nickel alloy is 92%-96%, the weight ratio of carbonyl iron is 2%-4%, and the weight ratio of carbonyl nickel is 2%-4%. The iron-nickel alloy contains 36% of nickel ...
