为了研究Fe对Al基非晶合金的影响,通过各种技术对Al84Ni10La6和Al84Ni9Fe1La6的结构与性能进行了研究.结果表明:加入1%Fe(摩尔分数)增加了结构因子中预峰的面积并降低了晶态与非晶态热膨胀系数之间的差异;加入1%Fe提高了Al-Ni-La合金的非晶形成能力、显微硬度、断裂韧性、电阻率、抗磁性和耐腐蚀性,这是由添加1%Fe引起的中程序及自由体积的变化导致的.

To study the influence of Fe addition on the Al-based amorphous alloys, the structure and properties of Al84Ni10La6 and Al84Ni9Fe1La6 alloys were investigated through various techniques. The results show that 1% Fe (molar fraction) addition increases the area of the pre-peak in the structure factor and decreases the thermal expansion coefficient difference between the crystalline and amorphous states. 1% Fe addition also improves the glass forming ability (GFA), micro-hardness, fracture toughness, electric resistivity, absolute diamagnetism and corrosion resistance of Al-Ni-La alloys, which is related to the changes of medium-range order and quench-in free volume caused by 1% Fe addition.
