In friction stir technologies (FST), the friction stir processing (FSP) is expected to be a promising microstructure refinement method for crystalline materials. In this study, we have applied the friction stir processing to a ZK60 magnesium alloy as a grain refinement method. In this paper, the distance between the tool centers of adjoining FSP passes, d, is discussed. The effects of d and the direction of FSP pass on mechanical properties are compared and discussed. Then, the effects of annealing temperature on relaxation of texture are discussed. We compared the annealed materials with the mechanical properties
