Experimental and Theoretical Investigation of Three Alloy 690 Mockup Components: Base Metal and Welding Induced Changes
Figure 7
The TT Alloy 690 DP bar had coarse grains and showed carbide coarsening associated with Ti(C,N) banding just like the CRDM2 tube. The magnification shows that the intragranular particle banding consisted of mainly orange Ti(C,N) precipitates and also of grey M23C6 carbides.
