| Abstract: | The systematic study has been made by the variations of contents of O in alloy powders and adding amounts of Mn for the effect on the mechanical properties of 93 W-Ni-Fe-Coalloy,as well as composition and content of W grains and binder phase,microstructure and fractograph,distribution of Mn,O and S and the type,structure,size,morphology and distribution of the inclusions formed by Mn and O and S in thealloy.The action and mechanism of Mn in W-Ni-Fe-Co seriesheavy alloys have been discussed.A technical way for the improvement of toughness of the alloys has been given. |
