Conclusions
-
1.
To ensure fairly high resistance of weldments to cracking during heating of precipitation-hardening alloys it is necessary to have high plasticity at aging temperatures.
-
2.
Alloy KhN63M9B2Yu was developed for welded structures operating at temperatures from −253 to +750° C. The alloy has a fairly high resistance to cracking during welding or during subsequent heat treatment.
