In addition, most of them contain 0.5 to 1.5% of B, and the (Ti + B) fi degree is in a relatively high range. These alloys are usually made by adding titanium fluoride alkali powder and borofluoride alkali powder to molten aluminum at a temperature range of 750 to 900°C and stirring to reduce the titanium and boron content in the powder and add it to the molten metal. After transferring and holding for several minutes, aluminum fluoride alkali, which is a byproduct after the reaction, is removed, solidified, and processed.

In the XTi-IKB alloy, 37% of the molten metal amount, A13XTi
-IXB alloy (27%) is added and reacted, so Ti-8 and Ti-Al compounds tend to grow coarsely in the molten aluminum, and these compounds not only have no refining effect but also It mixes with the lumps and forms inclusions, causing quality problems for plates, shapes, etc. Furthermore, aluminum fluoride-11 alkali, which is a by-product of the above reaction, is also generated in proportion to the addition of a large amount of flux (AI-5XTi-1
For χB alloy, 33% for product 1k [A13XTi
-22% for IKB alloy) Because the removal of C and C is not complete, these floating slags mix into the refined alloy as they are and become non-metallic inclusions in the ingot, making it difficult to separate the inclusions sufficiently. Because it is not easy to obtain appropriate cleanliness, quality problems are occurring as aluminum products become more precision processed and aluminum foil becomes thinner.
