Answer / sk singh
Normally during solidification (if the casting size is big)
cores has larger grain size than the grains at the surface
of casting. so if there is gradient in grain size is needed
across the casting, there must be uneven cooling rates
throughout the crossection. if we able to maintain a temp
gradient during heat treatment , then it is possible to have.

Answer / malayappan
The question is not clear. Is it the gradient from surface
to the core or from core to the surface. However, Any grain
refinement heat treatment is carried out to have a uniform
grain structure, like for exampling normalizing. It wmay
not be possible to have a gradient grain structure.

Answer / anil kamat
Yes , It is possible to have gradient in Grain size of
castings by heat treatment process . Addition of chills ,
localised cooling etc are some methods.
