Purpose and goal
The purpose of improving mechanical properties for today´s alternatives to aluminium alloys at temperatures up to 250 ° C while maintaining or improving room temperature properties has been partially fulfilled. Mechanical properties, in this case ultimate tensile strength, has surpassed the goal of a 20% improvement. However, the improved ultimate tensile strength comes with decreased ductility at room temperature.
Expected results and effects
Ultimate tensile strength has been improved by 47 % at 230 ° C and 22 % when tested at room temperature for the aluminium alloy produced for die casting. Ultimate tensile strength for the alloy produced for high pressure die casting has been increased by 27% at 230 ° C and by 8% at room temperature. However, the ductility when tested at room temperature have decreased.
Planned approach and implementation
The project has been carried out in two stages. Experimental casting in lab scale was carried out in stage 1. In stage 2, die casting and high pressure die casting were carried out at foundries in production-like conditions. Testing and analysis of the cast material produced was carried out in collaboration between the participating parties in the project.
