The mechanical properties, optical microstructure and textures of a continuously-annealed cold-rolled high strength structural steel were evaluated. The results show that the experimental steel has good balance of high strength and ductility, and the microstructure is composed of uniform, fine-grained ferrite and a little pearlite. The textures after recrystallization annealing are weak. The intensity of the strongest textures such as {114}<110> and {223}<110> are no more than 4. And the main {114}<110> and {223}<110> components are originated from the hot-rolling process and cold-rolling process, respectively, and preserved after annealing. The application of the experimental steel indicates that it can perfectly satisfy the stamping of some complicated structural parts in the automobile industry.

Due to the inherent properties of the process, arc-based generative manufacturing offers the possibility, of specifically applying different material properties locally. One possibility to realize this is the use of different materials. Three approaches are presented to illustrate this option. First, anisotropic behavior in the welding direction is generated. For this purpose, a FeNi36 is specifically combined with a low-alloy ultra-high-strength fine-grained structural steel filler metal. It will be shown that the integral component properties can be specifically adjusted in the welding direction. In addition, the metallurgical and welding characteristics will be discussed. As a second possibility, the use of well plasticizable materials to locally increase the material strength under cyclic loading with locally notched components is presented. For this purpose, an austenitic FeNi36 with good plasticizability and a good yield strength ratio for the application was applied to a fillet weld of a high-strength fine-grained structural steel in the weld seam toe. It is shown that the tolerable cyclic load can be improved by 35% by this procedure. Thirdly, it is shown that the required thickness of corrosion protection layers can be reduced by 50% through a targeted production sequence in arc-based generative manufacturing.
