Effect of cooling rate on the microstructure and hardness of austenitic stainless steel welds
The aim of this work is to study the effect of the cooling, rate on the microstructure and hardness of the melted material of welds in steels AISI 304 and AISI 316L. The increase of weld heat input, consequently the decrease in the cooling rate, produces only a smooth increase of the ferrite content and a small decrease of hardness in the melted material of autogeneous TIG welds.
