摘要

本文通过原位位移过渡成功地在钢/铝激光焊接-钎焊中引入硼。硼分布在FeAl3和Fe2Al5晶界界面，硼强化的晶界阻碍了裂纹扩展。引入B的接头的平均拉伸载荷提高了50%。

Strengthening of Fe-Al interfacial intermetallic compounds in steel / aluminum welding-brazing joints by introducing boron through in-situ displacement transition

In this paper, boron was successfully introduced through in-situ displacement transition in steel/Al laser welding-brazing. Boron was distributed in the interfacial FeAl₃ and Fe₂Al₅ grain boundaries, and grain boundaries strengthened by boron hindered the crack propagation. The average tensile load of the joint introduced with B was increased by 50 %.
