W-Ce alloys were researched to prepare high density and high calorific value active alloys.Porous W skeleton was prepared by isostatic pressing with W powder as raw material.Then the skeleton was sintered to improve the skeleton strength.Finally,W-Ce alloy with high density W as skeleton and active Ce as filling phase was prepared by liquid phase infiltration of Ce.The microstructure,properties and reactivity of W-Ce alloys prepared by different W skeleton preparation processes were studied.The results show that the density of W-Ce alloys is above 95%.The phase composition of the alloy is W and Ce,and no intermetallic compound is formed.The dynamic compressive strength ranges from 621 MPa to 905 MPa,and the dynamic compressive plasticity ranges from 20%to 30%.The W-Ce alloy has a lower reaction threshold.
