A STUDY ON SOLID MELT INTERFACES AND THE FORMATION OF [100] TEXTURE IN SOLIDIFIED FCC METALS/

The [100] texture of solidified fee metals, caused by the preferential (100) dendrite growth, could be closely related to solid/melt interfa ces which behave differently along different crystallographic orientat ion. The stability and roughness of {111} and {100} solid/melt interfa ces of fee metals were investigated using a modified Temkin multi-laye r model. It is demonstrated that {100} crystal/melt interface is more unstable and rougher than {111} interface. The effect of the stability of crystal/melt interface on the [100] texture formation in solidifie d fee metals has been analysed and discussed.
