Benefits of technology

This patented technology helps create pure metal alloys with fewer harmful substances from traditional methods like melting or casting processes without losing their quality. It also improves the efficiency at producing these materials while reducing costs associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the properties of certain types of metals such as tantalum or zirconia during their production processes without causing them from separating out into different phases when they are mixed together due to differences between crystal structures caused by changes made over time (cold work).

Embodiment Construction

[0028] Such as figure 1 As shown, the preparation method of the niobium aluminum alloy of the present invention at least includes the following steps: mixing niobium pentoxide, aluminum and a small amount of slag remover to form a mixed material; melting the remaining aluminum to form aluminum liquid; The material is added into the aluminum liquid, so that it can generate niobium through the aluminothermic reduction reaction, and evenly distribute in the aluminum liquid, and react with excess aluminum to form a uniform niobium aluminum alloy.

[0029] Such as figure 2 As shown, according to an embodiment of the present invention, the niobium-aluminum alloy preparation system includes a ball mill pressing granulation device 1, a smelting device 2, a vacuum and / or an inert gas input device 3, a stirring device 4, a temperature control device 5, and a weight Proportioning device6.

[0030] In one embodiment of the present invention, the niobium-aluminum alloy comprises the fol...

Abstract

The invention discloses a preparation method of a niobium-aluminium alloy. The preparation method is characterized in that the preparation method comprises the following steps that niobium pentoxide is mixed with aluminum and a small quantity of fluxing agent and deslagging agent to form a mixed material; surplus aluminum is smelted to form molten aluminum; and the mixture is added to the molten aluminum, and niobium is produced through an aluminothermic reduction reaction, is uniformly distributed in the molten aluminum, and reacts with surplus aluminum to form the niobium-aluminium alloy which is uniform in component. According to the niobium-aluminium alloy prepared by the method, niobium is distributed uniformly, the segregation degree of niobium is low, aluminum ignition loss is little, and the alloy eutectic point temperature is low, and the components are stable.
