| Abstract | The solidus, liquidus and volume of residual liquid were achieved by analyzing the solidification behavior of a sub-eutectoid U-Nb alloy. Results show that the dentritic crystal connects with each other and residual liquid is separated by solid phase during terminal solidification. Thus, serious micro-porosity form easily in isolated residual liquid area for the filling channels plugging and residual liquid unable to fill the pore, and the amount of porosity in casting is about 1.6% derived from theoretical calculation. The segregation coefficients of niobium at intermediate and terminal solidification are 0.16 and 0.11, respectively, which indicates that Nb is a strong negative segregation element and it severely clusters in the dendritic area. |
