Abstract Scope |
The development of high entropy alloys (HEAs) and compositionally complex alloys (CCAs) have broadened the possibilities of alloy design by exploring wider regions of solid solubility. With an ever-increasing demand for high-performance lightweight alloys, the concepts developed within HEAs/CCAs is implemented into the design approach of new high performance Al alloys similar to the extensively used A357 cast alloy. Developing an alloy with an increase in the thermal stability or specific strength, will give the possibility to reduce emissions within the transportation sectors, particularly within the aerospace industry. A selection of alloys was designed via high throughput screening to maximise solid solubility in an Al-7Si alloy. Microstructural and mechanical characterisation via SEM, EBSD, DSC, hardness and high temperature tensile testing revealed an increase in both strength and ductility from room temperature to 200°C over the comparable A357 alloy, without forming additional phases. |
