通过分析304型含铜奥氏体抗菌不锈钢的显微硬度、电阻率、电化学阻抗和晶格常数的变化，结合透射电子显微镜的观察，研究了该钢中铜的析出行为，表明该钢的这些性能随着时效时间的不同而有不同程度的变化。结果表明，显微硬度法和电阻率法均能较灵敏、准确地反映试验钢中铜的析出行为，指示析出的起点和终点，为新型抗菌不锈钢的研制提供了更简便、有效的手段。(C)2010爱思唯尔有限公司。保留所有权利。
Copper (Cu) precipitation behavior in a type 304 Cu-bearing austenitic antibacterial stainless steel was studied by analyses of variations in micro-hardness, electrical resistivity, electrochemical impedance and lattice constant of the steel, complemented with transmission electron microscopy (TEM) observation, showing more or less changes on these properties of the steel with different aging time. It was found that both micro-hardness and electrical resistivity measurements were relatively sensitive and accurate to reflect the Cu precipitation behavior in the experimental steel, indicating the beginning and finishing points of the precipitation, which are more simple and effective to be used for development of the new type of antibacterial stainless steels.
