Role of trace boron on microstructural evolution and mechanical performance of arc welded steel joints

This work explores how small additions of boron influence the microstructure and mechanical behavior of arc-welded mild steel joints. Welds produced without boron were compared with those containing 45 ppm and 47 ppm boron. Mechanical performance was evaluated using tensile, hardness, and Charpy impact testing, while m...
