Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 as shown, figure 1 reveals the control of TiB 2 Flowchart of the method for preparing an aluminum-titanium-boron alloy with an average nominal diameter of particle clusters. It includes the following steps:
[0022] Step S11 Adding liquid metal aluminum: In this step, aluminum metal is put into the above-mentioned induction furnace, and the next step is prepared to prepare the required aluminum-titanium-boron alloy. In the present embodiment, what is added is liquid aluminum, that is, the aluminum is melted in other places or equipment and then put into the above-mentioned furnace body. Like this, in the present embodiment, it is not necessary to use the induction furnace to melt the metal aluminum. Rather, it is only necessary to maintain the state or temperature of the aforementioned liquid aluminum. Of course, in other em...

The invention relates to a preparation method of an aluminum-titanium-boron alloy capable of controlling the average nominal diameter of a TiB2 cluster, comprising the following steps: heating liquid aluminum placed in an electric induction furnace to enable the electric induction furnace and the liquid aluminum to be kept for a first set time at a set temperature; adding an alloy material comprising potassium titanate and potassium fluoborate; and maintaining current passing through coils of the electric induction furnace, and acting on liquid alloy in the electric induction furnace to enable the electric induction furnace and the liquid alloy to be kept for a second set time at a set temperature. The preparation method of an aluminum-titanium-boron alloy capable of controlling the average nominal diameter of a TiB2 cluster in the embodiment of the invention has the following beneficial effects: a plurality of alternating magnetic fields are superposed in a furnace body to enable each part in the furnace body to be acted by magnetic field force and the average nominal diameter of the TiB2 cluster to be more tiny, thus improving grain refinement capability of the aluminum-titanium-boron alloy on aluminum or aluminum alloys.
Description
technical field [0001] The invention relates to the field of metallurgy, more specifically, to a method for controlling TiB 2 A method for preparing an aluminum-titanium-boron alloy with an average nominal particle diameter. Background technique [0002] Al-Ti-B alloy is an intermediate alloy that is widely used in aluminum processing worldwide and is the most effective for refining aluminum and aluminum alloy grains. Adding the above-mentioned aluminum-titanium-boron alloys to aluminum or aluminum alloys can refine the grains of the aluminum or aluminum alloys, thereby greatly improving their yield strength, calendering plasticity, and ductile-brittle transition temperature. It is used in many fields, such as aviation and so on. Potassium fluorotitanate and potassium fluoroborate aluminothermic reaction method is widely used in the world and effectively realizes the industrialization of aluminum titanium boron master alloy. This method produces a large amount of TiB 2 As...
