Abstract
Heat treatment of sheet steel is commonly performed in the automotive industry to save weight. However, current methods come with drawbacks such as energy usage and expensive tooling. This paper investigates the use of a novel localized heat treatment method and benchmarks three different methods for determining an optimal heat treatment pattern. The results show that the best performing method comes close to the strength full heat treatment, while only heating one-fifth of the area. The method is also applied to a more complicated part to validate the approach
