摘要: Abstract This paper reports the influence of heat treatment on mechanical properties, corrosion behavior and biocompatibility Zr 56 Al 16 Co 28 bulk metallic glass (BMG) investigated by dynamic analysis (DMA), electrochemical in vitro hemocompatibility vivo experiments. alloys with amorphous, semi-crystalline fully crystallized microstructures were obtained thermal as-cast BMG below or above transition temperature (T g ). The modulus slightly decreased increasing T whereas dramatically increased treated due to appearance crystalline phase. passivation potential did not change for samples heat-treated but significantly , which indicated that possessed better resistance than alloys. showed good hemolytic regardless microstructural condition presented lower rate their counterparts. In test revealed similar structurally relaxed Mice implanted BMGs degree inflammatory infiltration response compared mice results properties generally comparable its counterpart superior samples.
