Processes for forming blanks having tailored properties in localized areas are provided. The blanks are then formed into three-dimensionally shaped components (e.g., high-strength automotive parts). A sheet of high-strength metal alloy may be selectively heated in a first region to a temperature below a melting point of the metal alloy with a heat source, while a second region of the sheet adjacent to the first region remains unheated. The selective heating creates a first region of the metal alloy having at least one material property distinct from the second region. After the sheet is cut to form a blank, the blank comprises a portion of the first region and a portion of the second region. In this manner, a plurality of distinct tailored regions may be formed on each blank. The process may be continuous or semi-continuous and further include cutting of blanks from the sheet. High-strength structural components are also provided.
