摘要：

The surface roughness effect on 4 multiplied by 5MFS tool steel life is experimentally studied for low-cycle fatigue at normal and elevated (450 degree C) temperatures, characteristic of stamps. The surface factor may be calculated following a suggested procedure which is based on deformation interpretation of low-cycle failure and consideration of microunevenness values for a standard specimen and a specimen or structural element with a prescribed surface roughness.
