New classes of aluminium-magnesium-silicon alloys via scandium additions

该项目旨在建立所需的知识，以便能够使用钪(Sc)改善铝合金。运输部门的温室气体排放量占全球所有温室气体排放量的20%，使用铝来减轻车辆重量提供了大幅减少这些排放的潜力，但目前铝合金的性能不符合必要的要求。为了克服这一挑战，需要具有成本和性能最佳平衡的新型铝合金。这一领域的一个机会是使用SC，但到目前为止，高昂的SC价格限制了研究。随着澳大利亚最近发现了丰富的SC来源，SC的价格将会下降，成为一个可行的解决方案。这将确保澳大利亚在用于工程应用的先进铝产品领域处于领先地位，从而带来好处。

This project aims to establish the knowledge required to be able to improve Aluminium (Al) alloys using scandium (Sc). The transport sector accounts for 20 per cent of all greenhouse gas emissions globally, and the use of Al to reduce the weight of vehicles offers the potential to significantly reduce these emissions, however the properties of current Al alloys do not meet the necessary requirements. To overcome this challenge there is a need for new Al alloys with optimal balance of cost and performance. One opportunity in this area is the use of Sc, however the high Sc price has restricted research thus far. With the recent discovery of rich sources of Sc in Australia, the price of Sc will drop and become a viable solution. This will provide benefits by securing Australia’s position as a leader in the field of advanced Al products for engineering applications.
