The initiation and propagation mechanism of the overlapping zone cracking during laser solid forming of IN-738LC superalloy

The cracking mechanism, especially the initiation and propagation process of cracking, in the overlapping zone (OZ) of laser solid forming (LSF) of IN-738LC alloy was investigated. The results showed that both the solidification cracks and liquation cracks can be found in the OZ of the LSFed IN-738L...
