The microstructure of a metallic material is controlled to modify the final ultimate tensile strength of the material. The method involves the steps of continuously moving the material along a path past a heating means and a cooling means. The material is heated by the heating means to an initial temperature to change the material to a first microstructure. As material continues in motion this temperature is reduced by the cooling means according to a selected cooling pattern such that the material changes to a second microstructure that depends on the selected cooling pattern. The material is elongated as it is in motion during both the heating step and the cooling step.
