Research On The Method Of Preparation Of AZ31Magnesium Alloy Containing Ceirum And Lanthanum Rare Earth Oxide

The proliferation of the magnesium alloy which is the lightest metal extensivelyused in many fields. The papers add a Ce-La mixed rare earth oxide powderscontaining Ce、La alloy and successfully prepared a cerium-containing-lanthanumAZ31alloy with magnesium-the middle of the rare earth alloy AZ31alloy preparedorganizations and to compare the performance. Experimental studies found that addcerium-rich mixed rare earth oxide powder can also be obtained AZ31alloycontaining Ce、La, under the same Ce、La content, organization, performance andmagnesium-from the middle of the rare earth alloy AZ31alloy is similar.In the process of experiment, we first cerium-rich mixed rare earth oxide powderand a refining agent into a box-type furnace160°C insulation30min, amongsmelting process after they are uniformly mixed with the added to the solution. Thisexperiment through a set of orthogonal experiments to analyze the performance of thetwo methods prepared AZ31alloy, orthogonal experiments by controlling the threeinfluencing factors which are added the amount of rare earth, melting temperature,stirring time among the9experimental specimen. We can get optimal melting processby this group of orthogonal experiment; We detected9specimen composition,organization, rolling performance, tensile properties and oxidation resistance analysiscan see that we prepared in this way the composition of the AZ31alloy andmagnesium-the middle of the rare earth alloy AZ31alloy of the same composition;and adding rare earth alloy mechanical properties improve, such as rolling, tensileproperties of a certain level of improvement; At last the analysis of the oxidationproperties of the alloy can be found that the alloy was manufactured by two methods density of the oxide film is almost the same, which means that the the AZ31alloyoxidation resistance of the two methods was obtained similar.Through the experimental methods and analysis that we can use the Ce-La mixedrare earth oxide replaces magnesium-the middle of the rare earth alloy-performancesystem in excellent AZ31alloy. This can reduce the process of preparation of rareearth elemental not only saves energy, but also reduces environmental pollution at thesame time be able to significantly reduce the production costs.
