摘要：

The behaviour of hardmetals and cermets under cyclic bending has been investigated by a new experimental method. Both coated and uncoated materials have been tested, at temperatures varying between 25 degrees C and 900 degrees C. The results show a strong fatigue effect. The endured stress amplitudes and lifetimes are strongly reduced under cyclic loads in comparison to the behaviour under static Loads. Strong negative influences come from temperature and hard coatings. The conclusions advise the engineer to take fatigue into account in strength and lifetime calculations.
