T. Mohandas et al., A comparative evaluation of gas tungsten and shielded metal arc welds of a"ferritic" stainless steel, J MATER PR, 94(2-3), 1999, pp. 133-140
The effect of welding process shielding gas and the addition of gain refini
ng elements on the weld zone tensile properties of a ferritic stainless ste
el conforming to AISI 430 has been investigated. Cas tungsten are welds exh
ibiting equi-axed grain morphology had superior tensile and yield strength
compared to shielded metal are welds. The tensile ductility of gas tungsten
are welds was also on an average marginally greater than that of shielded
metal are welds. Welds in general showed low ductility compared to that of
the base metal. The addition of titanium and copper led to improved strengt
h over that of the base alloy. The observed properties could be correlated
to the austenite content and the fracture morphology. (C) 1999 Elsevier Sci
