Abstract Titanium alloys find extensive use in the aerospace and biomedical industries due to a unique combination of strength, density, corrosion resistance. Decades mostly experimental research has led large body knowledge processing-microstructure-properties linkages. But much existing understanding point defects that play significant role mechanical properties titanium is based on semi-empirical rules. In this work, we present results detailed self-consistent first-principles study was...
Ti-6Al-4V powder has been recycled 30 times in an electron beam melting system. A combination of microscopy techniques used to show that the a 35% higher oxygen content, and particles have more irregular morphology, narrower particle size distribution, much variable microstructure than virgin powder. The microstructures vary from martensitic α′ structure, which is identical powder, two-phase α + β structure. This variability related complex thermal history unmelted metal Despite these...
Laser powder bed fusion (LPBF) additive manufacturing (AM) has been adopted by various industries as a novel technology. Powder spreading is crucial part of the LPBF AM process that defines quality fabricated objects. In this study, impacts input parameters on spread density and particle distribution during are investigated using DEM (discrete element method) simulation tool. The simulations extend over several layers used to analyze packing variation in different at points along...
In this study, our goal is to design solid solution strengthened aluminum alloys for manufacturing technologies that involve high cooling rates. This investigation starts with an analysis of strengthening using first principles calculations determine elastic property changes and local lattice distortions from the introduction different elements into a host lattice. These results, coupled both equilibrium non-equilibrium solubility data, leads selection cerium cobalt as primary candidate...
This work aims at determining the effect that variations in material data have on predictions of growth morphologies for Ag-Cu system. The are based Kurz-Giovanola-Trivedi (KGT) model, which establishes quantitative relations between solid-liquid interface velocity, alloy composition, and temperature. These can be used to predict morphology constrained conditions. Material were extracted from available literature calculate changes Ag-5wt% Cu. When considering range reported values this...
