Summary: | The invention provides a hafnium-containing aluminum alloy and a preparation method and application thereof, and belongs to the technical field of alloys. The hafnium-containing aluminum alloy provided by the invention comprises the following elements in percentage by mass: 3-15% of Zn, 1-6% of Mg, 1-5% of Cu, 0.1-2% of Zr, 0.1-2% of Hf and the balance of Al. The specific content of hafnium is introduced into the aluminum alloy, the mechanical properties (such as strength and toughness) of the aluminum alloy can be effectively improved, the industrial price of hafnium is only one third of that of scandium, and therefore the aluminum alloy has wide industrial application prospects.
本发明提供了一种含铪铝合金及其制备方法和应用,属于合金技术领域。本发明提供的含铪铝合金,按质量分数计,元素组成包括:Zn3~15%,Mg1~6%,Cu1~5%,Zr0.1~2%,Hf0.1~2%,余量为Al。本发明在铝合金中引入特定含量的铪,能够有效提高铝合金的力学性能(如强度和韧性),且铪的工业价格仅为钪的三分之一,因此具有广阔的工业应用前景。 |
