There is a growing demand to produce parts from Hastelloy-X materials, which exhibit high unit cost per weight, by the selective laser melting (SLM) process. However, when material was employed, solidification crack occurred during SLM This cracking can be reduced or eliminated optimizing process parameters, such as power and scan speed, although optimization time- cost-intensive. In this study...

Abstract Temperature-time cycles are essential for the formation of microstructures and thus mechanical properties materials. In additive manufacturing, components undergo changing temperature regimes because track- layer-wise build-up. Because high brittleness titanium aluminides, preheating is used to prevent cracking. This also effects thermal history. present study, local solidification con...

Ductile cast irons (DCIs) are of increasing importance in the renewable energy and transportation sectors. The distribution morphology graphite nodules, particular formation degenerate features during solidification, dictate mechanical performance DCIs. In situ high-speed synchrotron X-ray tomography was used to capture evolution nodules solidification DCI, including effect carbon concentration...
