This study investigates fixed and moving mesh methodologies for modeling liquid metal–free surface deformation during the induction melting process. The numerical method employs robust coupling of magnetic fields with hydrodynamics turbulent stirring metal. Free tracking is implemented using level set (LS) arbitrary Lagrangian–Eulerian (ALE) formulation. model’s geometry operating parameters are designed to replicate a semi-industrial furnace. Six case studies analyzed under varying melt...
Nickel-based superalloys are widely employed to manufacture aero-engine turbines due their high mechanical strength and resistance corrosion creep. Vacuum Induction Melting (VIM) is a suitable manufacturing technology because of the reactive nature alloying elements; however, melting process time-consuming energy-demanding. This research focuses on increasing overall efficiency in two ways. Initially, studying influence metal-containing crucible composition thermal properties melting. In...
The hammer forging is a well-known technology to incrementally produce geometrically complex forgings by compressing the material against dies using several forming blows. When aeronautical components with this technology, it crucial control final grain size of part since variable highly influences high temperature low cycle fatigue properties. Nowadays, common practice use finite element models coupled recrystallization optimize process parameters and strategy. However, very important...
Titanium investment casting is one of the leading and most efficient near-net-shape manufacturing processes, since complex shape components are possible to obtain with a very low amount material waste. But melting these reactive alloys implies usage specific technologies such as Induction Skull Melting (ISM) method. In this work ISM was extensively studied aim deepening characteristics method improving too energy efficiency overall process performance. A 16 segment copper crucible 3 turns...
Investment casting of magnesium is a well suited process for the production aeronautic and automotive components. But still, this has not been properly developed. One reason that are reactions between Mg melt ceramics mould produce non-desired oxide layer on part surface. These can be inhibited by use silica-free slurries with higher stability than conventional ones. Another way using inhibitors, chemical compounds based in fluorides react melt, creating protective surface casting. With aim...
In casting parts, due to the manufacturing process, presence of defects such as porosity, inclusions and oxide films is unavoidable. All these irregularities have a negative effect on component performance. Several works demonstrated that, among them, porosity especially detrimental fatigue properties. As most failures nucleate at surface material, or near roughness become an extremely important factor in determining strength cast components. Very little research has been conducted into...
