Technical field
The present invention relates to field of metal alloy technology, belong to a kind of aluminum alloy materials specifically through microalloying.
Background technology
The result of literature survey shows that rare earth has removal of impurities in aluminium alloy, effect such as degas, go bad.The research to the rare earth aluminium alloy aspect abroad concentrates on the aluminium alloy that contains Sc.The domestic relevant application of rare earth in aluminium alloy is started in phase later 1970s, the metamorphism, application and rare earth the aspects such as application in architectural aluminum section of rare earth in electrician's aluminium alloy that are used for casting Al-Si alloy at rare earth have obtained good effect, and certain research has also been carried out in Rare-Earth Ce, the effect of Y in the Al-Si alloy.What more than use and study usefulness mostly is mishmetal, though domesticly in recent years done certain research in effects in aluminium alloy such as single rare earth Y, Sc, Er, but with the Er, the aluminium alloy of Zr complex intensifying of trace, the research in especially strong, anti-corrosion in a large amount of Al-Mg-Mn that use in fields such as naval vessel, aircraft, vehicle, the weldable aluminium and use and do not see any report.Our Al-Mg-Mn that discovers rare earth Er, Zr complex intensifying has significant strengthening effect, and its strengthening mechanism is mainly due to crystal grain thinning and form equally distributed tiny Al at intracrystalline
3Er phase, the interpolation of Zr not only can play the effect of crystal grain thinning, and can further improve the solid solubility of Er, help separating out the Al that more small and disperseds distribute
3The Er phase.Al

3The Zr structure is identical, belongs to Pm3m spacer (simple cube), and lattice parameter can play the effect that refined crystalline strengthening, dispersion-strengthened and second are strengthened mutually near Al.
Summary of the invention
Problem to be solved by this invention is to seek the element that is applicable to the aluminium alloy microalloying, and alloy matrix aluminum is played strengthening effect, thereby improves the performance of aluminium alloy.
Er with trace provided by the present invention, the Al-Mg-Mn alloy of Zr complex intensifying, it is characterized in that, in the matrix of Al-4.5%Mg-0.7%Mn (weight percent) alloy, added 0.01～0.6% rare earth Er that accounts for the final product gross weight and the transition element Zr that accounts for final product gross weight 0.01～0.2%.

The Al-Mg-Mn alloy of this Er, Zr complex intensifying is by existing melting and complete processing preparation, with fine aluminium (99.99%), pure magnesium (99.99%), and be starting material through Al-10.02%Mn, Al-4.52%Zr, the Al-6%Er master alloy of vacuum melting, adopt the ingot metallurgy method, insulating covering agent covers, the degasification refining, melting forms ingot casting in crucible electrical resistance furnace.Ingot casting crop behind 450 ℃～480 ℃/15～25 hours homogenizing annealings mills face, diathermanous (470 ℃ 1 hour) and hot rolling, cold rolling get the 1.5mm heavy-gauge sheeting.Hot rolled total reduction 70%～85%, hot rolling are after process annealing (470 ℃ 1 hour), and cool to room temperature is later on cold rolling, cold roling reduction 67%～80%.
The present invention has been owing to added micro-rare earth Er and transition element Zr, improved Al-4.5%Mg-0.7%Mn aluminium alloy mechanical property behind cold rolling attitude and the stabilizing annealing when room temperature greatly, makes tensile strength of alloys (σ
b) and yield strength (σ
0.2) all improving 15～17%, it is constant substantially that its unit elongation (δ) keeps.Simultaneously, the Al-4.5%Mg-0.7%Mn alloy of process microalloying also has higher mechanical behavior under high temperature, can be used as the heat-resisting aluminium alloy that is no more than 200 ℃ of use temperatures and uses.The improvement of aluminium alloy capability mainly is because Er and matrix have formed the Al of coherence or half coherence behind the microalloying
