Problems solved by technology

Nb-Zr10 alloy is the most widely used niobium-zirconium alloy. With the increase of its application fields, the requirements for niobium-zirconium alloy are getting higher and higher. There are electron beam melting, hydrogenation treatment, dehydrogenation and Niobium-zirconium alloys are prepared by isostatic pressing at room temperature. When electron beam melting is used, the melting point of niobium is nearly 3,00

Embodiment Construction

[0012] An embodiment of the present invention is described below: the preparation method of niobium zirconium 10 alloy,

[0013] 1) Fully mixing 90 parts by weight of metal niobium bars and 10 parts by weight of metal zirconium bars to form mixed raw materials;

[0014] 2) Put the mixed raw materials into the vacuum melting furnace, and evacuate to 10 -3 Pa, the voltage rises to 25-35 kV, and the voltage is 14000 amps for one smelting, followed by cooling in the furnace to form a primary alloy ingot;

[0015] 3) The voltage of the primary alloy ingot is raised to 25-35kV again, and the voltage is 14,000A for secondary purification and smelting, and the secondary alloy ingot is formed by cooling with the furnace; since the melting points of niobium and zirconium are quite different, the use of a vacuum melting furnace can avoid alloying. volatilization of zirconium;

[0016] 4) The secondary alloy ingot is hydrogenated with fully saturated hydrogen in a vacuum furnace, the pr...

Abstract

The invention provides a preparation method of niobium-zirconium 10 alloy. The preparation method comprises the following steps: fully mixing niobium bars and zirconium bars, putting in a vacuum melting furnace, and carrying out two-times melting; then carrying out hydrogenation and dehydrogenation treatment, finally pressing powdery alloy by using a cold isostatic press so as to obtain an ingot blank, and then putting the ingot blank on a hot isostatic press and pressing so as to obtain the ingot blank finished product. The alloy ingot blank prepared by the method is uniform in structure, so that the structure segregation problem is solved; the ingot blank is prepared by the high-temperature pressing, so that the problems of sintering deformation, shrinkage cavity and the like are solved; the rate of finished products is increased; the density of the ingot blank finished product is greatly increased; the ingot blank finished product has a very high practical value.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and particularly relates to a preparation method of a niobium zirconium 10 alloy. Background technique [0002] Niobium-zirconium 10 alloy is an alloy composed of metal zirconium added to metal niobium. Adding zirconium to niobium can improve the strength of the alloy without affecting the plasticity and processability of the alloy. Zirconium can also improve the oxidation resistance and alkali metal resistance of the alloy. corrosive properties. Nb-Zr10 alloy is the most widely used niobium-zirconium alloy. With the increase of its application fields, the requirements for niobium-zirconium alloy are getting higher and higher. The niobium-zirconium alloy is prepared by isostatic pressing at room temperature. When using electron beam melting, because the melting points of niobium and zirconium are inconsistent, the melting point of niobium is nearly 3,000 degrees, and the melti...
