Microstructural effects on tension behavior of Cu-15Ni-8Sn sheet

The effects of systematic changes in microstructure/heat treatment on the mechanical behavior of Cu-15Ni-8Sn (Pfinodal®) were evaluated in uniaxial tension. Multiple samples were tested and fracture surfaces were analyzed via scanning electron microscopy (SEM). Significant effects of cold work and heat treatment on the tension behavior were obtained and rationalized based on the mechanisms of failure, revealed by SEM, for this system.
