摘　　要：考察和评价了铸轧法和挤压法生产铜管管坯和管材的组织和性能,并分析了水平连铸铜管坯的组织性能以及管坯和管材的拉伸断裂机制。The microstr uc ture and mechanical properties of TP2copper tubes produced by cast-roll proces ses and extrusion processes have been observed and evaluated,the tensile fractu re mechanisms of the tube products and the tube billets been analyzed,it was fo und that the cast-roll copper tube products exhibit as good microstructure and mechanical properties as extruded copper tubes.
