Numerical research on the formation of casting defects during the solidification process of CuAl10Fe3Mn2 alloy

Abstract

The paper presents a numerical analysis of the solidification process of the CuAl10Fe3Mn2 alloy and a study of the influence of the occurring casting defects. CuAl10Fe3Mn2 alloy (the so-called aluminium bronze) is characterized by high strength as well as hardness and can be a cheaper substitute for many materials used in industry. The article covers the topic of the filling process of the bell-casting mould and the solidification process of the CuAl10Fe3Mn2 alloy. The filling process was presented using the finite volume method and the volume-of-fluid method model. This phenomenon was considered a time dependent solution with a pressure-based solver and an enthalpy-porosity formulation. The developed numerical model allows for the analysis of both turbulent and laminar flow.
