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.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
