TiB2-reinforced composite coating by gas tungsten arc welding

Journal of Materials Science, 2009
In situ synthesized TiB2-reinforced Fe-based coating was fabricated by gas tungsten arc welding (GTAW) on AISI-4340 steel substrate using cheaper Fe–Ti, Fe–Cr, Fe–W, Fe–B alloys and B2O3 powders. The effects of processing parameters on the coating were investigated experimentally.

Insight Into Puncture‐Induced Thermal Runaway in Lithium‐Ion Batteries to Reduce Fire Risks in Electric Vehicle Collisions

Battery Energy, Volume 4, Issue 6, November 2025.
This review examines nail penetration‐induced thermal runaway (TR) in lithium‐ion batteries, analyzing experimental and modeling studies on critical factors—battery materials, nail properties, state of charge, and penetration dynamics. It also explores internal short‐circuit modes, TR severity, and safety solutions such as advanced separators, non ...

Effect of helium gas on arc characteristic in gas tungsten arc welding.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1985
Effects of helium gas on the maximum arc pressure and on the critical travel speed to melt a base metal were investigated in GTA welding.Results were obtained as follows;(1) The critical speed in helium (He) gas arc is much higher than in argon (Ar) gas arc.
