Abstract
Wire arc additive manufacturing (WAAM) offers great potential for the production of automobile components due to its high material deposition rates, low costs and design freedom. In order to meet the requirements regarding surface integrity and lifetime, the parts must be mechanically finished after WAAM. However, the subsurface properties (e.g. residual stresses) and consequently the application behavior are significantly influenced by the mechanical finishing process. Thus, the effects of deep rolling and heat treatment on the residual stresses and lifetime of AlSi12 and AlSi10Mg parts produced by WAAM are investigated and the results are presented in this paper. Deep rolling was found to induce compressive residual stresses into additive manufactured AlSi12 and AlSi10Mg workpieces. Furthermore, deep rolling increased the lifetime of the WAAM components significantly. With a combination of a heat treatment and subsequent deep rolling AlSi10Mg workpieces were manufactured securely fail-safe.

N1 - Funding Information: The investigations prove the positive effect of deep rolling on the residual stresses and application behavior of WAAM aluminum components. In this context, deep rolling ensures and increases the performance of AM components significantly. Further investigations on the optimized deep rolling parameters for AlSi10Mg should be conducted. In addition, further research is required regarding the influence of the building direction on the application behavior of workpieces out of AlSi10Mg. The influence of the WAAM process parameters on the application behavior of AlSi12 components should be investigated. For a reliable prognosis of the lifetime of AlSi12 components optimal WAAM parameters must be known. Targeted goals in terms of residual stress state and application behavior should be determined. DR process parameters which meet the targeted goals can be identified afterwards. This should be executed by taking the field of tension defined by productivity, cost and resource efficiency and quality into account. A detailed knowledge about the choice of deep rolling process parameters would be beneficial to the users and for the market breaktrough of WAAM.

The authors want to thank the Federal Ministry for Economic Affairs and Climate Action (BMWK) for funding this project.
