Summary

The effects of various trace elements on properties and fracture modes of heavy alloys are described. It has been found that tungsten heavy alloys can be embrittled by traces of Al, Si and P, while various other impurities are ineffective. In all cases embrittlement is caused by deterioration of the interfacial strength between binder and W grains. Al is not embrittling itself but preserves the oxygen, which is the embrittling element. Fractography by SEM is recommendable for correctly assessing the significance of the AES results.
