Abstract
The microstructure of three 12% Cr steel weld metals with
different nickel and nitrogen contents was studied in as-welded
condition and after postweld heat treatment with and without
intercooling. Tensile strength and impact toughness of the
weld metals were investigated in different postweld heat treatment
conditions. In weld metals heat treated without intercooling,
austenite decomposed by a eutectoid reaction that resulted
in M sub 23 C sub 6 aggregates around retained delta -ferrite.
Two morphologies of M sub 2 N and MN precipitates were found
in a low-dislocation alpha -ferrite. In was concluded that
these phases were also transformed from austenite. In weld
metals heat treated with intercooling, M sub 23 C sub 6 precipitates
were smaller and more homogeneously distributed. Different
MN precipitates were found in the tempered martensite. The
fracture mode of the weld metals at room temperature was mainly
transgranular cleavage with some fibrous fracture. Intercooling
treatment improved Charpy impact toughness of the 12% Cr steel
weld metals substantially. It was found that the important
microstructural factors affecting the impact toughness of
the weld metals which were heat treated without intercooling
were the sizes of the alpha -ferrite grains, nonmetallic inclusions,
and M sub 23 C sub 6 aggregates. For the weld metals heat
treated with intercooling, the factors which affect the toughness
of the weld metals were the sizes of martensite packets and
nonmetallic inclusions. |
