| Abstract (English): |
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. [ABSTRACT FROM AUTHOR] |
| Abstract (Bosnian): |
Legirajući elementi prisutni i u alatnom čeliku i u aluminijumu utiču na rastvaranje alatnih čelika u rastopljenim legurama aluminijuma. Ova studija ima za cilj da predvidi kako legirajući elementi u alatnom čeliku, posebno nikl (Ni) i molibden (Mo), utiču na formiranje sloja interakcije između alatnog čelika i rastopljene legure aluminijuma. Interakcioni sloj između ispitivanih alatnih čelika Dievar ili RavnekHD i legura aluminijuma Al99.9 i Al99.7 sastoji se od intermetalnog i kompozitnog sloja. Interakcioni sloj između ispitivanih alatnih čelika i legure aluminijuma AlSi12 sastoji se od tri različita interakcijska sloja. Alatni čelik za rad u toplom stanju RavnekHD pokazuje bolju otpornost na rastvorljivost u različitim legurama istopljenog aluminijuma. Glavni legirajući element u ispitivanim alatnim čelicima koji utiče na rastvaranje alatnog čelika u rastopljenom aluminijumu je Ni, koji je u većim količinama prisutan u RavnekHD. Ni se ugrađuje u matricu i inhibira difuziju železa i aluminijuma kroz matricu. Mo u Dievar alatnom čeliku formira karbide, omogućavajući lakšu difuziju ovih elemenata kroz Fe-matricu. Otpornost u rastopljenim aluminijumskim legurama pokazuje čelik za rad u toplom stanju RavnekHD. [ABSTRACT FROM AUTHOR] |
