Recent advances on the mechanical behavior of zinc based biodegradable metals focusing on the strain softening phenomenon

Structural and temporal dynamics analysis of zinc-based biomaterials: History, research hotspots and emerging trends

“…Additionally, dynamic recrystallization can cause changes in dislocation density, resulting in the occurrence of these two phenomena [ 89 , 90 ]. Forming high-density twin boundaries to suppress dislocation motion, altering the mode of dislocation motion, improving grain boundary stability through segregation, and introducing low-energy grain boundaries are effective methods to overcome strain softening and creep [ 65 , 118 ]. The low melting point of zinc alloy also leads to extensive atomic migration at room temperature under non-strain and load conditions, resulting in phase transformation during storage and consequently changes in the physical properties.…”

“…This kind of non-uniform deformation is detrimental to Zn based devices or implants, which will possibly lead to unexpected failure. According to Huang et al [ 17 ], Zn based BMs can be divided into three categories on the basis of tensile strength and uniform elongation terms, i.e. Zn–Li based alloys with high strength and low uniform elongation, Zn–Mg based alloys with medium strength and uniform elongation, and Zn–Cu, Zn–Mn, Zn–Ag based alloys with low strength and high uniform elongation.…”
