Abstract
The present invention relates to the field of metal and alloy technology. The Al-Er alloy features that to aluminum or aluminium alloy, is added rare earth element Er in the amount of 0.01-1.0 wt%, preferably 0.1-0.3 wt%. The Al-Er alloy is prepared by adding vacuum smelted Al-Er intermediate alloy white smelting Al or Al alloy. The addition of Er can improve greatly the mechanical performance of Al alloy, including 20 % raised tensile strength and yield strength, and raise the re-crystallization temperature of Al alloy. The Al-Er alloy may be used in structure member in aeronautical, asthonautical, building, automobile and other industries.
Description
One, technical field
The invention belongs to field of metal alloy technology.
Two, background technology
The result of literature survey shows that external research aspect rare earth aluminium alloy is few, and only report also only only limits to the research at 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.Yet what more than use and study usefulness mostly is mishmetal, promptly uses single rare earth also to be only limited in the Al-Li alloy.And lack applied research for the most basic occurrence status of relevant rare earth in pure Al and aspect pure Al Effect on Performance.Find that at present rare earth Er has significant strengthening effect to pure Al, its strengthening effect mainly comes from thin crystalline substance and forms equally distributed tiny Al at intracrystalline
3The Er phase.Al
3Er and Al
3Sc and Al
3The Zr structure is identical, belongs to Pm3m spacer (simple cube), and lattice parameter is near Al.Deducibility thus, behind Sc, Er is expected to become the effective alloying element that improves aluminium alloy capability, and any report is not seen in this effect of Er in aluminium alloy so far as yet.
Three, summary of the invention
Problem to be solved by this invention is to seek a kind of rare earth element that is applicable to the aluminium alloy microalloying, and the aluminum or aluminum alloy matrix is played strengthening effect, thereby improves the performance of aluminium alloy.
Al-Er alloy provided by the present invention is characterized in that having added the rare earth Er of 0.01～1.0% (weight percent) in the matrix of aluminum or aluminum alloy.
The optimum content scope of above-described rare earth Er is: 0.1～0.3% (weight percent).
The preparation method of this Al-Er alloy realizes by adding through the Al-Er of vacuum melting master alloy in the aluminum or aluminum alloy fusion process.
The present invention has improved the mechanical property of fine aluminium and aluminium alloy greatly owing to added rare earth Er, makes tensile strength of alloys (σ
b) and yield strength (σ
0.2) all improve more than 20%, its unit elongation (δ) remains unchanged or slightly raises.Simultaneously, rare earth Er has also obviously improved the recrystallization temperature of aluminium and aluminium alloy.The improvement of aluminium alloy capability mainly is because Er and matrix have formed the Al of coherence or half coherence
3The Er fine particle.
Four, description of drawings:
Fig. 1: the hardness of pure Al and Al-0.1Er and annealing temperature relation curve;
The hardness of Fig. 2: Al-3Mg and Al-3Mg-0.1Er and annealing temperature relation curve.
Five, embodiment:
Example 1: adopt plumbago crucible and iron mould casting legal system to be equipped with alloy cast ingot, raw materials used is the master alloy of 99.99% rafifinal and Al-6%Er.Ingot casting makes the 2mm heavy-gauge sheeting through hot rolling-process annealing-cold rolling (80%).Cold rolling attitude and the annealed state tensile property of four kinds of Er content alloy and pure Al have been listed in the table 1.Therefrom as can be seen, Er can improve tensile strength and the yield strength of cold rolling attitude and the pure Al of annealed state to some extent, and along with the increase of Er addition, the intensity increase rate also increases, but increase trend is slowed down.Er is little to the plasticity influence of pure Al.
The tensile property of pure Al of table 1 and Al-Er alloy different states
The method that adopts hardness and metallographic to combine has been determined the recrystallization temperature of alloy.Metallographicobservation shows that after annealing in 225 ℃, 1 hour, obvious recrystallize has taken place pure Al, and the recrystallize sign has just appearred in the Al-0.1Er alloy; Through annealing in 400 ℃, 1 hour, the obviously alligatoring of the crystal grain of pure Al, and the crystal grain of Al-0.1Er alloy is tiny equiax crystal.Fig. 1 is hardness and the annealing temperature relation curve of pure Al and Al-0.1Er.Can determine the initial recrystallization temperature T of pure Al and Al-0.1Er by Fig. 1
sAnd end of a period recrystallization temperature T
f(shown in arrow among Fig. 1) adds 0.1%Er, and the recrystallization temperature of pure Al has been improved about 50 ℃.
Example 2: adopt plumbago crucible and iron mould casting legal system to be equipped with alloy cast ingot, raw materials used is 99.5% Al, 99.5% Mg and the master alloy of Al-6%Er.Ingot casting is made the 2mm heavy-gauge sheeting through hot rolling-process annealing-cold rolling (80%).Cold rolling attitude and the annealed state tensile property of two kinds of Er content alloy and comparative alloy Al-3Mg have been listed in the table 2.As can be seen, in the Al-3Mg alloy, add micro-its cold rolling attitude of Er and annealed state tensile strength and yield strength and all be significantly improved, but the unit elongation of cold rolling attitude alloy has decline slightly, and the unit elongation of annealed state alloy remains unchanged substantially.Along with the increase of Er addition, the intensity of alloy also has increase trend.
The tensile property of table 2 Al-Mg and Al-Mg-Er alloy different states
Fig. 2 is hardness and the annealing temperature relation curve of Al-3Mg and Al-3Mg-0.1Er.Can determine the initial recrystallization temperature T of Al-3Mg and Al-3Mg-0.1Er by Fig. 2
sAnd end of a period recrystallization temperature T
f(shown in arrow in 2), the Er of adding 0.1% makes the recrystallization temperature of Al-3Mg alloy improve more than 50 ℃.
