摘要

    摘要
  • 摘要: 针对铝/钢熔钎焊界面金属间化合物在SEM,EDS,XRD界面测试研究的基础上,确立了界面由Fe2Al5、FeAl3等金属间化合物组成. 在此基础上采用蒙特卡罗方法,建立了铝/钢界面铝、铁扩散及Al-Fe化合物生长模型,并进行了数值分析和对比研究. 结果表明,所建立的模型能够很好地反映钢侧Fe2Al5的生长,铝侧FeAl3离散存在,且金属间化合物层的厚度接近试验测量结果.
    Abstract: Measurements and analysis with SEM, EDS, XRD confirmed that the intermetallic compounds in aluminum/steel MIG-brazed interface consisted of Fe2Al5 and FeAl3 phases. Based on Monte Carlo method, the diffusion of Al and Fe in aluminum/steel interface and growth model for Al-Fe intermetallic compounds were established, and numerical analysis and comparative study were conducted. The results show that the proposed model could well reflect the growth of Fe2Al5 phase on steel side, and FeAl3 discretely existed on aluminum side, and the thickness of the intermetallic compound was close to the experimentally measured results.
