Quantification of residual stresses via selective pre-sintering in laser powder bed fusion of Ti-6Al-4V
Large residual stresses as a result of rapid, highly localised melting and solidification are a common feature of Ti-6Al-4V components manufactured by laser powder bed fusion (LPBF), which may cause irreversible damage to components during manufacturing or in end-use applications. To overcome this, heat treatments are often used post-processing to release residual stress accumulated during processing. More recently, heat treatment methods have been successfully implemented in situ for the reduction of residual stress through reduced thermal gradients, thereby improving the mechanical properties of as-built components. In this proposal, we plan to investigate the influence on residual stress of a novel multi-laser process, called laser pre-sintering (LPS). LPS has promising benefits from a manufacturing perspective, but its influence on residual stress has never been studied, and therefore its true impact is not yet understood.
