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.

晶粒细化用于提高铝合金的性能，但是在高硅铸造合金和当前基于二硼化钛的晶粒细化剂之间缺乏相容性。硼化铌基晶粒细化剂的开发有助于改善铸造合金的性能。性能的提高应该允许减轻汽车铸造部件的重量，这有利于燃油经济性和电动汽车的自主性。
