主 题：Biodegradable Zn alloys Alloy design Second phase Microstructure Comprehensive properties
摘 要：Alloying combined with plastic deformation processing is widely used to improve mechanical properties of pure ***-cast Zn and its alloys are *** plastic deformation processing,no effective method has yet been found to eliminate the brittleness and even endow room temperature *** phase,induced by alloying,not only largely determines the ability of plastic deformation,but also influences strength,corrosion rate and *** second phase is important for designing biodegradable Zn *** this review,knowledge related to second phases in biodegradable Zn alloys has been analyzed and summarized,including characteristics of binary phase diagrams,volume fraction of second phase in function of atomic percentage of an alloying element,and so *** about second phases in Zn-Li,Zn-Cu and Zn-Fe systems have been settled down,which benefits future *** effects of alloying elements and second phases on microstructure,strength,ductility,corrosion rate and cytotoxicity have been neatly ***,Mn,Li,Cu and Ag are recommended as the major alloying elements,owing to their prominent beneficial effects on at least one of the above *** future,synergistic effects of these elements should be more thoroughly *** other nutritional elements,such as Fe and Ca,refining second phase is a matter of vital concern.
