Description
Technical field
The present invention relates to magnesium alloy plate rolling forming technology, belong to metallic substance manufacturing technology, be specially a kind of manufacturing process of magnesium sheet metal.
Background technology
Magnesium alloy as a kind of Novel light metal application material, have that specific tenacity is high, proportion is little, high damping, high heat conduction and damping property good, be easy to the advantages such as recovery.Therefore, magnesium alloy obtains and applies widely in aerospace, automobile, 3C Product etc. in recent years, is known as in the industry the most promising lightweight metallic substance.But magnesium is cubic close packed structure, its processing characteristics when temperature is lower is not good, and this causes very large difficulty to the preparation of its sheet material.But go out a kind of very important intermetallic composite coating product in shaping prod as metallic substance, sheet material is a kind of important supplies of intermediates, and its application can simplify the technical process in the deep processing of magnesium metallic substance greatly, simplifies complicated technology, thus reduction manufacturing cost, broadened application scope.
A kind of quality and alloying constituent of plastic working ability of alloy are closely related.According to the impact of alloying constituent alloy plastic working ability, alloy is divided into casting, extruding, rolling and wrought magnesium alloy product.Although extruding, rolling and forging are the deformation processing technique of magnesium metal, its machining deformation mechanism has relatively big difference.The extrusion processing only of some alloys, some alloys can not be processed in rolling, and the AZ31 alloy as common is a kind of common extruding alloying constituent, and ZK60 is a kind of common extruded alloy composition.Domestic common extrusion magnesium alloy is mainly MB1, MB5 etc., and the alloy that can be used in plate rolling processing is mainly MB3, MB8 and MB22 etc.Generally speaking, the kind of trade mark deformed Mg metallic substance is less, and sheet deformation magnesium metallic substance is then less.From the viewpoint of design of material, the more few processing being more beneficial to magnesium sheet metal of the content of thick second-phase in alloy, otherwise cause the cracking of alloy in the operation of rolling.
Zn is a kind of common alloy element, and it significantly can improve mobility and the intensity of alloy.More about the magnesium metal species containing Zn at present, concentrate in Mg-Zn-RE (Zr), Mg-RE-Zn (Zr) alloy system at present too much, RE is that rare earth element is called for short.As studied the alloys such as more Mg-Zn-Y or Mg-Y-Zn at present, in such alloy, contain the phase that I (accurate brilliant)-phase or W-phase or LPSO (accumulation of long period fault)-equal three classes are comparatively given prominence to.The maximum feature of this kind of nascent second-phase is exactly that size is too thick, skewness, and not easily thermal treatment, the Cracking Failure during this directly causes alloy rolling to be processed, squeezing prod for this kind of such alloy of feature is more, which has limited its commercial applications in automobile, aerospace etc.
Therefore, obtain can rolling processing alloying constituent most important.At present as a kind of magnesium metal ingredient that effectively can be used for roll forming.The existing Zn alloy that contains is except not easily disappearing except molten ternary phase containing above-mentioned three kinds thick, and another feature is exactly that Zn, RE (rare earth) content is high, and Zn content is high causes hot tearing in alloy processing, and the high cost of alloy that causes of RE content is too high.Select rational alloying constituent, namely avoid alloy to cause performance on the low side because alloying ingredients is lower, avoid again alloy because Zn content is higher processing characteristics deviation.Therefore select the addition of Zn and RE, being that exploitation is a kind of rolling can shape the key of magnesium metal.And the rolling temperature interval of Mg-Zn-RE magnesium alloy is little, more difficult control, qualified yield rate reduces, and therefore the rolling condition of research acquisition Mg-Zn-RE magnesium alloy seems most important.
In view of magnesium metallic crystalline structure feature, therefore adopt the high-quality magnesium sheet metal of the very difficult acquisition of quick rolling technology of low temperature, two-forty, high single pass heavy deformation.So, hot rolling process under hot conditions is mainly adopted in magnesium sheet metal manufacture, general hot-rolled temperature is higher is 350 ~ 500 DEG C, single pass heavy deformation is less is 5 ~ 10%, in this, processing conditions causes the working (machining) efficiency of magnesium metal lower, the object that rapid processing is shaped cannot be reached, therefore urgently develop a kind of can the metal rolled technique of magnesium of roll forming fast.
In addition, due to the close-packed hexagonal structure of magnesium metal, in the course of processing, also has the problem of wide-thin sheet material processing difficulties.Therefore, in the operation of rolling, except considering rolling temperature, speed and single pass heavy deformation etc., also to coordinate the burning optimization on line problem in the operation of rolling, heat treatment technics is namely utilized to improve the working plasticity of metal, acquisition crystal grain is tiny, homogeneous microstructure, anisotropy obvious sheet material pre-treatment product, therefore considers processing request and the dimensions of sample, seems particularly important in the operation of rolling to the burning optimization on line of sample.But, almost do not relate to the content of this respect in the metal rolled technique of current magnesium.
Relating to one in the present invention newly can roll forming Mg-Zn-Er sheet alloy and preparation method thereof fast, its composition and mass percent are 0 ~ 5.0wt.%Zn, 0 ~ 1.0wt.%Er, Zn and Er mass percent sum is not less than 0.5% and does not exceed 5.0%, and its surplus is Mg.This alloying constituent is obviously different from the Mg-Zn-RE alloy such as (RE=Y, Er, Gd rare earth element) containing I phase, W phase of current report, the addition of rare earth is less, concentrate in the category of microalloying, and the overall addition of Zn and RE has certain restriction, namely not higher than 5.0%.In conjunction with specific rolling technology, be illustrated as a kind of novel rolling technology in this patent, its principal feature is the segmentation rolling that high/low temperature combines, i.e. high temperature height deflection rolling sequence, deflection rolling sequence in low temperature, the dividing point of high and low temperature is dynamic recrystallization temperature line ± 25 DEG C of alloy.Texturing temperature interval is divided into high temperature, cold zone, high-temperature zone height deflection, the lower deflection in cold zone, and rolling speed is higher, concentrates on 1.0 ~ 2.5m/s, and in the operation of rolling, adopting multidirectional rolling technique.This alloy related in this patent and rolling technique thereof are magnesium metal different from the past and sheet material technology of preparing thereof, its can obtain under quick preparation technology smooth surface, thinner thickness and without fission cracking high-quality magnesium sheet metal.
Summary of the invention
Relate to a kind of new Alloy And Preparation Method in the present invention, provide a kind of magnesium metallic substance that can be rolled into sheet material fast.Mg-Zn-Er alloy in invention, its alloying ingredients scope is lower, and containing the comparatively precious metal such as Zr, be a kind of cheap again can the magnesium metallic substance of rolled plate fast.Breach current magnesium Plastic Deformation not enough, making magnesium sheet metal process preparation, forming difficulty, is a kind of magnesium sheet metal material possessing application prospect.
