| Abstract: | Much attention is paid on the twins in pure Cu.The classification and crystallographic structure of twins are introduced.The effect of twins on strength,ductility,strain hardening,strain rate sensitivity,plastic deformation mechanism and electrical resistivity(or conductivity) is summarized,and the mechanisms underlying these phenomena are discussed.At the same time,it is discussed what should be studied further in the Cu with twins.It is eventually pointed out that introducing high density of twins in grai... |
