This study aims to investigate the evolution of crystallographic texture and local strain distribution in friction-welded 316L stainless steel cylinders produced by the additive manufacturing method (AM)-laser powder bed fusion (L-PBF). By combining AM and solidstate welding, the work will provide insight into texture changes at the welding area during micro-tensile loading. The novelty lies in computing strain fields directly from texture analysis, an approach not yet realized experimentally, which could pave the way for nondestructive 3D strain cartographies. The results are expected to advance in-situ characterization methods and establish a foundation for joining dissimilar alloys in future applications.
