In-situ electron optical measurement of thermal expansion in electron beam powder bed fusion
Additive Manufacturing, 2021 Abstract Thermal expansion plays an important role during additive manufacturing by electron beam powder bed fusion because it strongly affects the quality of the manufactured parts. However, prediction and control of thermal expansion is a difficult task due to the high complexity of part geometries and the corresponding temperature distribution ...

Advanced Engineering Materials, EarlyView.A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel
Advanced Engineering Materials, EarlyView.Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...
