Description
技术领域technical field
本发明属于非晶材料制备领域，具体涉及一种Al-ETM-LTM-TE多元铝合金及其制备方法。The invention belongs to the field of preparation of amorphous materials, and in particular relates to an Al-ETM-LTM-TE multi-element aluminum alloy and a preparation method thereof.
背景技术Background technique
1965年，Predecki和Giessen等人首次通过熔体极冷法制备出了铝基非晶Al-Si。到1981年，Inoue等人成功制备出完全的非晶结构铝合金系Al-Fe-B和Al-Co-B，但这种成分的非晶因为非常脆并没有得到重视。之后又得到了非晶合金系列Al-Fe-Si，Al-Fe-Si，但仍然很脆，所以人们认为脆性是非晶铝合金的一种特征。然而1987年Inoue在Al-Ni-Si和Al-Ni-Ge合金系中得到了具有良好韧性的非晶，接着在Al-ETM-LTM系列三元合金系中制备得到了具有良好韧性的非晶铝合金系。In 1965, Predecki and Giessen et al. prepared aluminum-based amorphous Al-Si for the first time by melting extremely cold method. By 1981, Inoue et al. successfully prepared complete amorphous structure aluminum alloys Al-Fe-B and Al-Co-B, but the amorphous composition of this composition has not been taken seriously because it is very brittle. Afterwards, the amorphous alloy series Al-Fe-Si and Al-Fe-Si were obtained, but they were still very brittle, so people believed that brittleness was a characteristic of amorphous aluminum alloys. However, in 1987, Inoue obtained amorphous with good toughness in Al-Ni-Si and Al-Ni-Ge alloy systems, and then prepared amorphous with good toughness in Al-ETM-LTM series ternary alloy system Aluminum alloy series.
非晶铝合金因具有高的比强和优异的耐蚀等性能，在航天、航空、国防、运输、军用和民用装备等方面将发挥重要作用。近些年来，非晶铝合金作为一种新型的非晶合金引起材料研究者的普遍关注。目前制约铝基非晶合金应用的主要限制是非晶合金形成能力较弱，对其理论研究的不够深入和透彻，因此，仍无法制备较大尺寸的非晶铝合金，韧性良好的非晶铝合金的开发利用更是少之又少，生产成本高。Amorphous aluminum alloy will play an important role in aerospace, aviation, national defense, transportation, military and civilian equipment due to its high specific strength and excellent corrosion resistance. In recent years, amorphous aluminum alloy, as a new type of amorphous alloy, has attracted widespread attention from material researchers. At present, the main limitation restricting the application of aluminum-based amorphous alloys is that the formation ability of amorphous alloys is weak, and the theoretical research on them is not deep and thorough enough. Therefore, it is still impossible to prepare larger-sized amorphous aluminum alloys and amorphous aluminum alloys with good toughness. The development and utilization of these materials are even less, and the production cost is high.
