Abstract
The present invention relates to ferro-aluminium, it is characterized in that containing magnesium in the alloy, composition range is as follows:
Al Mg Fe
14.17 surplus in the of 0.0002～0.02
The present invention has improved room temperature use properties and high temperature process performance, and ferro-aluminium is realized scale operation, and improving lumber recovery has very significance.
Description
The present invention relates to ferro-aluminium, particularly magniferous ferro-aluminium.
It is good that intermetallic Fe-Al compound has a fusing point height, light specific gravity, middle hot strength, and series of advantages such as antioxidant anticorrosive ability excellence have the great potential that becomes the new application structured material.Fe particularly
3The Al lower cost for material, thereby range of application might be more more extensive than other intermetallic compound, but Fe
3The Al room temperature is very crisp, is difficult to use.Adopt a lot of methods to overcome Fe in the world
3The room temperature fragility of Al, however at present as yet the someone put forth effort to study Fe
3The high-temp plastic of Al, the effective element Cr that improves temperature-room type plasticity has obvious effect to the high-temp plastic cunning.
The object of the present invention is to provide a kind of ferro-aluminium with good plasticity.
To the effect that of the present invention, alloy contains following element (weight percent)
Al Mg Fe
Surplus in the of 14～17 0.0002～0.02
Key of the present invention is Fe
3Added an amount of magnesium in the Al base alloy, the optimum content scope of magnesium is 0.0002～0.02wt%, and magnesium is not to be evenly distributed in Fe
3In the Al base alloy, auger analysis shows that magnesium gathers partially at crystal boundary, transmission electron microscope observing is found, magnesium increases crystal boundary and coordinates the intracrystalline deformation ability, make dislocation in passing the continuous sliding deformation of crystal boundary, so just easily cause boundary stress to concentrate, crackle also just is difficult at the crystal boundary forming core, thereby makes stretching plastic high significantly.Experimental result shows and adds after an amount of magnesium, has not only improved temperature-room type plasticity, also makes Fe
3The plasticity of Al under hot processing temperature (850 ℃) has improved more than 40%, is up to 62%.Fe provided by the invention
3The Al alloy can also contain one of B, Cr, Nb, Mo element or its combination, and its composition scope exists
B Cr Nb Mo
0.4～0.6 2～6 0.5～1.0 0.5～1.5
B wherein can strengthen the crystal boundary crystal grain thinning.Cr can increase the superdislocation and decompose width, makes slip line become tiny and the change song, thereby has reduced reverse domain boundary energy.In addition, Cr changes the character of oxide film, and protecting materials avoids being subjected to the infringement of water in the environment.Mo, Nb play the effect of solution strengthening, and in addition, Nb also forms Fe
2The Nb strengthening phase is stated in detail below in conjunction with embodiment and to be chatted the present invention.

Roll 1 normal temperature 467 550 3.4
3 normal temperature 387 533 4.9
5 normal temperature 465 577 5
The present invention has not only improved temperature-room type plasticity, and has improved high-temp plastic, has improved room temperature use properties and high temperature process performance, to reaching scale production, improves lumber recovery, and the broadened application scope has very important significance.
