Dynamic Behavior of Repaired metals using Electron Beam Additive Manufacturing
ORAL
Abstract
It is well-known that additive manufacturing alters the microstructure of materials and can lead to varying damage morphologies in spall recovery experiments. While there have been many works to investigate the dynamic response of components/coupons metals that are manufactured completely using additive manufacturing, there are almost no studies to investigate the dynamic response of a hybrid component/coupon built using traditional techniques and repaired using additive manufacturing. In this work, indents of different depths were systematically manufactured on the surface of wrought 316L SS plate. These defects were then repaired using 304L SS wire with the electron beam additive manufacturing technique and subjected to spall recovery experiments. The results highlight minor changes in the spall strength but a larger effect of the repaired region on the overall damage morphology.
