Investigation of size effect on flow stress of Cu-3wt.%Ag-0.5 wt%Zr thin sheets at room and cryogenic temperature based on geometrically necessary dislocation evolution behavior

Investigation of size effect on flow stress of Cu-3wt.%Ag-0.5 wt%Zr thin sheets at room and cryogenic temperature based on geometrically necessary dislocation evolution behavior

The influence of the grain sizes ranging from 23.4 to 69.2 μm on mechanical properties of Cu-3wt.%Ag-0.5 wt%Zr thin sheets was investigated by conducting uniaxial tensile experiments at room temperature (RT 298 K) and cryogenic temperature (CT 77 K). At RT, the strength and ductility of the sheet de...
