Grain refinement is used to increase the performance of aluminum alloys, but there is a lack of compatibility between high silicon foundry alloys and current grain refiner based on titanium diboride. The development of a new grain refiner based on niobium boride can help improve foundry alloys. The performance increase should allow weight reduction in car casting components which is beneficial to the fuel economy and electric vehicle autonomy.

谷物细化用于提高铝合金的性能，但是高硅铸造合金与基于二硫乙烷的当前谷物炼油厂之间缺乏兼容性。基于硼化氮化物的新谷物炼油厂的开发可以帮助改善铸造合金。性能提高应允许减轻汽车铸造组件的体重，这对燃油经济性和电动汽车自主权有益。
