Abstract

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 %.

期刊介绍： Materials Science and Engineering A provides an international medium for the publication of theoretical and experimental studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. Appropriate submissions to Materials Science and Engineering A should include scientific and/or engineering factors which affect the microstructure - strength relationships of materials and report the changes to mechanical behavior.
