Abstract (AI)
Results of investigations of electron beam welding of large components of VZh172 alloy, determination of the optimum heat treatment conditions of the welded section, and the mechanical properties of the welded joints and microstructure of the metal of the welded joint and the parent metal are presented.
Key Findings
1
Electron beam welding of large components made from VZh172 nickel superalloy was investigated and characterized.
2
Mechanical properties of the welded joints were measured and reported.
3
Microstructure of both the welded joint metal and the parent VZh172 metal was analyzed and described.
4
Optimal heat treatment conditions for the welded section of VZh172 alloy were determined.
