Abstract

In order to study the forms of boron in Al-B alloys with lower boron content, and expand the application scope of Al-B alloys with lower boron content. Al-1B alloy was prepared by mechanical alloying and vacuum sintering, the formation and evolution mechanism of boron in Al melt were analyzed in detail. Owing to the high concentration gradient of boron at a certain point in the Al melt, AlB₁₂ is easily formed at first and then peritectic reaction between AlB₁₂ and Al happened forming AlB₁₂@AlB₂ composite structure.The AlB₁₂@AlB₂ composite structure is easily reserved and keeps stable in Al-1B alloy. During the boronization process, AlB₂ reacts with transition metal elements, and AlB₁₂ remains in the Al melt.The study is beneficial for improving the efficiency of boronization treatment.
