| Abstract: | The lifetime of the dies is an important factor in raising the economic efficiency in the production. Through the macroscopic analysis as well as metalloscopy on the failure status of the cold forging die destined for manufacturing the copper contact heads of electric switches, the paper reaches the conclusion that the irregular distribution of the carbides will cause fatigue breaking, and the improvement measures so as to control the quality of material and improve the heat treatment technology are proposed. |

| Keywords: | fatigue fracture stress concentration carbide multiple-origin fatigue carbide distribution. |
