Description
Technical field
The invention belongs to metal material processing technical fields, and in particular to a kind of using copper to do middle layer to prepare zirconium steel compound
The method of plate.
Background technology
Zirconium is a kind of rare metal, has the advantages that easy processing, corrosion resistance are good and thermal neutron absorption cross section is low etc., extensive use
In nuclear industry.But in recent years, it has been found that the corrosion resisting property of zirconium is answered better than stainless steel, titanium, nickel alloy so zirconium is more and more
For industries such as oil, chemical industry.Zirconium clad steel plate may replace pure zirconium and be used to manufacture pressure vessel, not only reduce manufacturing cost, and
And zirconium resource is greatly saved.So zirconium and being connected in engineering for steel are an important technologies, there is presently no find one kind
Method of great satisfaction.There are certain difficulties for the connection of zircaloy and steel, this is primarily present two aspect reasons：First, crisp
Property intermetallic compound formation so that the mechanical strength and corrosion resistance of connector reduce；Second is that the thermal expansion system of two kinds of materials

The result shows that：Use copper as the zirconium steel clad steel plate (such as Fig. 4) that middle layer successfully obtains different shear strengths.Copper
After middle layer and base material are reacted at 700 DEG C, the diffusion layer of multilayered structure is obtained.From SEM photograph it can be seen that (such as Fig. 1-
3) it is, from left to right Q345, conversion zone and zirconium successively, copper intermediate layer reacts more violent with zirconium, and reaction layer thickness is wider, and copper
Middle layer and steel conversion zone obtained by the reaction are relatively thin.By Fe-Cu binary phase diagramls it is found that solubility of the Fe in Cu is smaller, reaction
It is extremely limited；And in Zr-Cu binary phase diagramls, Zr is reacted with Cu can obtain ZrCu, Zr2Cu and Zr3Cu8Equal multiple compounds.
When middle layer is 0.03mm, if apparent crackle occurs in the conversion zone in Fig. 1, zirconium clad steel plate shear strength only has
36.7MPa.And when middle layer is 0.06mm and 0.09mm, such as the conversion zone flat smooth in Fig. 2 and 3, do not split significantly
Line；The shear strength of zirconium clad steel plate is up to 61.4MPa, it is seen that zirconium clad steel plate can be significantly improved by increasing intermediate layer thickness
Bond strength.
In short, the fusing point of fine copper is about 1083 DEG C, and while no largely addition noble metal, the copper foil of this method use
Diffusion required temperature is greatly reduced, the time required to shortening diffusion, maintains higher shear strength.
Although embodiments of the present invention are described in detail, it should be understood that, without departing from the present invention's
In the case of spirit and scope, can embodiments of the present invention be made with various changes, replacement and change.
