| Summary: | The alloying elements present in both tool steel and aluminium are influenced in the dissolution of tool steels in molten aluminum alloys. This study aims to predict how the alloying elements in the tool steel, particularly nickel (Ni) and molybdenum (Mo), impact the formation of the interaction layer between the tool steel and the molten aluminium alloy. The interaction layer between the investigated tool steels Dievar or RavnexHD and the aluminium alloys Al99.9 and Al99.7 consists of an intermetallic and a composite layer. The interaction layer between the investigated tool steels and the AlSi12 aluminium alloy consists of three different interaction layers. The hot-work tool steel RavnexHD shows the better solubility resistance in various molten aluminium alloys. The main alloying element in the tool steels investigated that has an influence on the dissolution of tool steel in molten aluminium is Ni, which is present in higher amounts in RavnexHD. Ni incorporate in the matrix, and inhibits the diffusion of iron and aluminium through the matrix. Mo in Dievar tool steel forms carbides, allowing easier diffusion of these elements through the Fe-matrix. The resilience in molten aluminium alloys is demonstrated by Ravnex HD tool steel for hot work. |
