外文摘要：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.
