A novel scheme for weld microstructure control using cryogenic cooling

A novel scheme for weld microstructure control using cryogenic cooling

In this work, the preliminary result on the effect of cryogenic cooling on grain growth in weld is reported. Ferritic stainless steel weld produced under TIG torch in argon environment is cooled in liquid nitrogen. The weld structure is characterized using LOM, SEM and EDX spectroscopy. The results...
