The Evolution of Micromechanical Properties for Zr-Based Metallic Glass Induced by Laser Shock Peening

The micromechanical properties of Zr-based metallic glass (MG) induced by laser shock peening (LSP) were studied through the use nanoindentation. serrations in representative load-displacement ( P-h ) curves exhibited a transformation from stairstep-like to ripple-shaped untreated zone region, which implied an increase plastic deformation ability material after LSP. Significant hardening was also observed impact zone, can be attributed effect compressive residual stress. Both hardness and region indicate excellent LSP on investigated MG, provide new way study mechanism glasses further understanding plasticization.
