据美国田纳西州橡树岭国家实验室报导,该实验室开发出一种显示较高延性和冲击韧性的铁铝合金。从这类材料的典型脆性等级来看,这种铁铝合金获得了超出预期的延性和冲击韧性。该合金含有40at％的Al,通过对加工诱发显微结构和Mo、Zr及C的微合金添加物的适当控制,提高了它的拉伸延性。具有200mm或更大晶粒尺寸的铸造合金在室温大气中可获得高达4～5％的拉
According to the Oak Ridge National Laboratory in Tennessee, the United States, the lab developed an aluminum-iron alloy that showed higher ductility and impact toughness. Judging from the typical brittleness level of such materials, this ferrous-aluminum alloy achieves beyond the expected ductility and impact toughness. The alloy contains 40 at% Al, and its tensile ductility is enhanced by proper control of the process-induced microstructure and the micro-alloying additions of Mo, Zr and C. Cast alloys with a grain size of 200 mm or more can draw as high as 4 to 5% at room temperature in the atmosphere
