Gravity-induced buoyancy, inevitable in most solidification processes, substantially alters the dynamics of crystal growth, such that incorporating fluid flow models is crucial to understand and predict key aspects microstructure selection. Here, we present a multi-scale Dendritic Needle Network (DNN) model for directional includes buoyant liquid, apply it range alloys growth conditions. After ...

Materials science is highly significant in space program investigation, energy production and others. Therefore, designing, improving predicting advanced material properties a crucial necessity. The high temperature creep corrosion resistance of Ni-based superalloys makes them important materials for turbine blades aircraft engines land-based power plants. investment casting process costly time...

A ?-analogue of the superalloy CMSX-4 that does not contain strengthening ??-phase and only consists ?-solid solution nickel has been designed, solidified as single-crystals different orientations, tested under creep conditions in temperature range between 1150 1288 °C. The tests have revealed a very high anisotropy this alloy, was previously found for at supersolvus This could be explained by ...
