Surface nano-hardness and microstructure of a single crystal nickel base superalloy after laser shock peening
Author: Update times: 2017-04-28                          | Print | Close | Text Size: A A A

Nanoindention tests and SEM microstructure observations were conducted on a single crystal nickel base superalloy after laser shock peening (LSP). Distinct surface hardening behavior was found to occur under the selected LSP technology. A large discrepancy in γ areas happened on laser shocked regions and the large plastic deformation embodied in γ phases’ deformation brought a significant hardening effect.

 

This work was published on Optics and Laser Technology,2017,91:116-119.titled Surface nano-hardness and microstructure of a single crystal nickel base superalloy after laser shock peening.
