Carbide Precipitation in the Heat Affected Zone of a GTA Weld in 21-6-9Stainless Steel.

摘要

Grain boundary precipitation was observed in a multipass GTA weld in 21-6-9stainless steel. The precipitate was identified by electron diffraction as M sub 23 C sub 6 -type carbide. The presence of these carbide particles did not cause intergranular attack in standard corrosion tests. (ERA citation 04:043386)
