State of the Art in Sheet and Bulk Metal Forming Techniques

Topic Information

Dear Colleagues,

The forming production of sheet metal and bulk components is a highly specialized and automated process today. Science and industry work closely together to constantly establish new processes to be more productive and economic. The change in forming technology due to the new challenges of globalization, sustainability, and the change in mobility can be addressed in this Special Issue. The worldwide challenges for production and forming technology in particular, due to the reasons mentioned above, are constantly driving researchers and industry to improve existing processes. State-of-the-art approaches for modern forming technology as well as new solutions in forming technology are of interest to this Special Issue. Topics from sheet and bulk metal forming to material characterization and numerical investigations for forming processes can be addressed in this issue.

The presented work is aimed at the evaluation of the cold bending capacity of high-borated austenitic stainless steel sheets. Due to their excellent neutron-absorbing capability, borated stainless steels belong to the group of tailor-made structural materials widely used for vertical storage baskets for holding spent nuclear fuel assemblies in cooling pools at dry or wet storage facilities. The basket consists of individual fuel assembly cells. Each polygonal cell is usually welded from several steel strips. It would be advantageous to use bent steel semi-product to avoid welded seams as much as possible. Welded seams are difficult to make, and moreover, they are susceptible to corrosion. However, high-borated stainless steels, because of their boron content, show limited hot and cold workability. Thus, their cold bending capacity would be the primary issue. Their austenitic matrix with embedded hard and brittle boride particles is prone to the evolution and fast propagation of dimple transgranular fracture. This work is focused on the bending aspects of borated steel sheets with respect to the most commonly used hexagonal cell geometry. Experimental results provide practical recommendations for the rack design. The damage criterion has also been proposed using FEM simulations in DEFORM^®. Full article
