Softening and structural instability mechanism of biodegradable Zn-0.45Mn alloy at different heat treatment temperatures

Strengthening Mechanism of Rotary-Forged Deformable Biodegradable Zn-0.45Li Alloys

“…During extrusion, the surface of the workpiece is subjected to a large external force, and its surface energy storage is large. Therefore, recrystallization occurs first at the part where the energy storage is large [29]. After recrystallization, new grains with low energy storage in the microstructure are formed, and the grains are uniform and continuous equiaxial crystallization.…”

“…At this time, the proportion of recrystallized grains in the R3 alloy increased substantially, and the grains were uniform and exhibited continuous isometric crystallization (Figure 4). Recrystallization consumed the stored energy [29], so the deformed grain grew to a regular shape. The size of the recrystallized grains was highly related to the deformation degree and the size of the original grains.…”

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

“…The mechanical stability of zinc alloy is of vital importance for its practical applications, and there is a growing body of research focused on investigating strain softening, creep, and ambient temperature aging phenomena associated with it [ [113] , [114] , [115] ]. Strain softening refers to the phenomenon where the stress needed for further deformation of the material after one or multiple loading and unloading cycles is smaller than before [ 114 ].…”
