The Microstructures and Mechanical Properties of a Novel Biomaterial Mg-Zn-Sr Alloy Sheet during Aging Treatment

Abstract:

Mg-Zn-Sr alloy sheet; biomaterial; aging treatment; tensile property Abstract. The microstructures and mechanical properties of a novel biodegradable Mg-Zn-Sr alloy sheet aged at 175°C had been studied. The results indicate that the grain size of the casting alloy Mg-Zn-Sr is changed with the change of content of element Sr, and while it is 1.0 (wt.)%, smaller average grain size is gained which is 38μm, as well as it is increased to 1.5 (wt.)%, the grain size is coarsen obviously. The phase precipitated in the alloy sheet is sufficient and distributed in the uniform style at 175°C for 8h which gained the preferable mechanical properties, which the tensile strength reaches 230MPa, hardness 76.1HV as well as prolongation ratio 12.7%.
