Abstract
The effect of Mg and Ti addition on the solidification macrostructure of ferritic stainless steel was evaluated in order to obtain fine equiaxed grains. Equiaxed solidification was promoted by adding Mg and Ti. Ti addition affects the amount of TiN as a nucleation agent of d -Fe and the increase in constitutional undercooling. Mg addition produces spinel oxide in the molten steel, which accelerates the TiN formation. [Al] content also have an influence on the equiaxed grain formation.
