Enhancing Mechanical Properties of Mg-6Zn Alloy by Deformation-Induced Nanoprecipitation

doi:10.1007/s40195-020-01144-7

Abstract

Abstract:

We presented the solution of deformation-induced precipitation after homogenization to enhance the mechanical properties of Mg-6Zn alloys. The results show that the improved strategy exhibits more effective strengthening role than grain refinement methods based on low-temperature severe plastic deformation under the same strain. The low-temperature deformation with larger extrusion ratio results in massive nano-sized precipitates and excellent mechanical properties with the yield strength of 355 MPa and the ultimate tensile strength of 405 MPa. The increased mechanical properties are strong and tough enough to resist the stress and not be worn away when the alloy nail penetrates through the pig thigh bone, potentially extending more orthopedic surgery applications for Mg-Zn alloys.

Key words: Mg-6Zn alloy, Equal channel angular pressing, Deformation-induced precipitation, Severe plastic deformation, Mechanical property
