Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Enhancing Solar Still Performance Using Vacuum Pump and Geothermal Energy
Energies, 2019 Improvement in the performance of a solar still is investigated with the integration of a geothermal cooling system and a vacuum pump. Geothermal cooling is simulated to provide a cold, effective underground water temperature, which could reach 15⁻ ...

, 2020 Recently, alternative techniques have been used in conjuction with conventional baking methods in order to reduce baking time and energy consumption, the first being the use of a low-pressure or vacuum during baking. This process involves part-baking at atmospheric pressure followed the application of a partial vacuum (20-60 kPa) during the latter part

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

CFD Simulation of Heat and Mass Transfer during Vacuum Cooling Process for Cabbage
Zhileng xuebao, 2012 Effective vacuum cooling simulation has the advantage of low cost and short period, and therefore is important in theory and application. Based on the theories of unsteady heat transfer and mass conservation, a mathematical model developed by CFD ...

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
