• Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys (2019, background): “ntinuous films extending over several grains, which appears to be highly detrimental to the structural integrity of the build. The typical criterion for non-weldability, namely the content of (Ti+Al) [2], does not seem to apply here. In the alloy that we investigated, this criterion is superseded by”

• Current Status and Perspectives on Wire and Arc Additive Manufacturing (WAAM) (2019, background): “Residual stresses are determined by their characteristic length: type I are macro-stresses varying over the dimensions of the component; type II are intergranular stresses; type III are formed at an atomic scale [116,117].”
