A new preparation method for porous iron-based superalloy materials

Journal Article


Abstract


  • The porous iron-based superalloy materials have been prepared through the Kirkendall effect and using Fe-Cr-W-Ti-Y alloy powder adding Fe/Al mixed powder (with atomic ratio of 3:1) as raw materials. The effect of Fe/Al mixed powder content on the open porosity of porous iron-based superalloy materials was investigated. The results show that the addition of Fe/Al mixed powder can significantly increase the open porosity of the sintered compact. However, there is not a strictly linear increment rule between the Fe/Al mixed powder content and the open porosity. As added 15% (mass fraction) Fe/Al mixed powder, the sintered compact has the maximum open porosity of 33%. With the Fe/Al mixed powder content in the range of 15%-45%, the open porosity of the sintered compact decreases with the Fe/Al mixed powder content increasing.
