(1998 Vol.30-No.3)PERFORMANCE OF SURFACE-ENGINEERED HOT FORGING DIES

摘要

Forging dies are known to fail by four principal mechanisms -wear, thermal fatigue, mechanical fatigue and plastic deformation [1]. Details of some of the factors that contribute to these mechanisms and the reduction in die life are discussed in detail in [2]. A research team from CSIRO Manufacturing Science & Technology has been working with companies from the Australian Forging Group (AFG) on aspects of forging technology. The first project, completed in 1996, focused on improvements to forging dies, including studies of modified surfaces using different treatments and fatigue modeling.
