Microstructure, Carbides, Stainless, WeldingAbstract
A study on the microstructure of welded stainless steel AISI 430 with AISI 420 after GTAW welding process is discussed. Characterization techniques as optical microscopy and scanning electron microscopy (SEM) were used to observe the presence of carbides or precipitates that may affect the toughness of the joint due to the high amount of alloying elements in solid solution. These properties were evaluated and analyzed with mechanical tests.
