A method of making billets, whereby a composite billet is produced by continuous casting or rolling, which billet is star-shaped in cross section and has at least two ray members disposed symmetrically relative to the central longitudinal axis of the composite billet; the base of each star ray member of the composite billet at the place of its juncture with the central portion thereof is selected to be 0.72 to 2.3 of the ray member height, the other base being 0.5 to 1.0 of the ray member height, the lateral sides of the ray member may differ in length; the segregation zone is caused to concentrate in the central portion of the composite billet selecting appropriate relationship between geometric dimensions of the composite billet and by creating favorable conditions for producing the composite billet; thereafter, the ray members are severed from the central portion of the composite billet by means of rolls in a rolling mill, this being performed by subjecting one of the lateral sides of the ray member to the action of an appropriately grooved roll.
