SOLIDIFICATION BEHAVIOURS OF A SINGLE-CRYSTAL Ni-BASE SUPERALLOY UNDER LATERAL CONSTRAINTS
单晶 Ni 基高温合金侧向约束条件下的凝固行为

Solidification behavious and solute redistribution of a single-crystal nickle-basesuperalloy under lateral constraints were investigated.The experimental results show that thereare strong influence on the solidified microstructure,the solute segregation and the soluteredistribution.In substance,the effect of later constraints,i,e.the changes of transverse section,on the solidification of single-crystal nickle-base superalloy was the effect of the parameters ofcocal solidification.The results of this paper is of an important guide significance in solidifiedmicrostructure control and the product of single-crystal nickle-base superalloy.
