Study on Micro-Hardness and Electrical Conductivity in as Cast Cu-Fe-P Alloys
The micro-hardness and electric conductivity was studied in as cast alloy Cu-Fe-P alloys which were solution treated at 980°C and aging treated at 400-800°C for 1-20 hours. The micro-hardness peak value was 180 HV and the conductivity peak value was 65% IACS. The hardness and the electric conductivity all depended on precipitation principally. The addition of C in Cu-Fe-P alloy reduced the grain size and accelerated precipitation which resulted in enhancing hardness and electric conductivity together.
