Description
(1), affiliated technical field
The present invention relates to a kind of standard model of differentiating aluminium, particularly a kind of Al-Li alloy spectral standard sample.
(2), technical background
At present, the Al-Li alloy is a kind of new shape material, its production and exploitation, must strictly control desired chemical ingredients, and the chemical ingredients of control Al-Li alloy just must have corresponding with it standard model, technician's according to standard sample drawing curve, and then determine the chemical ingredients of the Al-Li alloy that institute produces or develops according to working curve, with this as the whether qualified standard of definite quality product.Existing aluminum alloy standard sample does not all contain the Li element, and these standard models generally are prepared from through operations such as melting, adjustment chemical ingredients, casting, homogenizing processing, extruding and sawings successively.Want to mix the Li element in aluminium, it is not all right adopting this preparation technology, and its reason is: the Li element is in fusion process, very easily by scaling loss, make that the Li element does not reach design requirements in the last standard specimen, and the Al-Li fluid surface can oxidation in crystallizer, have a strong impact on the quality of standard specimen.Existing preparation method also exists such deficiency: what adopted in casting is common semicontinuous casting method, and it is the aluminium water of adjusting to be flowed directly into crystallizer cast, and not stopping in the centre, finishes until casting; This casting makes the easy drawing crack of ingot casting, and is difficult to be shaped.
(3), summary of the invention
Purpose of the present invention just provides a kind of Al-Li alloy spectral standard sample that evenly contains the Li element.
Another object of the present invention provides the preparation method of this Al-Li alloy spectral standard sample.
Al-Li alloy spectral standard sample described in the purpose of the present invention is the chemical element that evenly contains following total weight percent in fine aluminium:
