Summary of the invention
The technical problem that the present invention solves there is provided a kind of low magnetic, High-strength NiW alloy composite baseband with cube texture.
Another technical problem that the present invention solves there is provided the preparation method of NiW alloy composite baseband of a kind of low magnetic, high strength, strong cubic texture, this preparation method simplifies preparation technology, reduce cost, improve production efficiency, the application requiring of more areas can be met.
Technical scheme of the present invention is: a kind of High-strength NiW alloy composite baseband with cube texture, be composited by outer and sandwich layer, it is characterized in that: the described composite baseband skin W atomic percentage conc that to be original material be adopts vacuum induction melting to obtain is the NiW alloy of 6% ~ 7%, described composite baseband sandwich layer is original material to be the W atomic percentage conc adopting vacuum induction melting to obtain be 9% NiW alloy.
The preparation method of High-strength NiW alloy composite baseband with cube texture of the present invention, is characterized in that comprising the following steps:
(1), the structure design of compound billet
The NiW alloy bar being 6% ~ 7% by the W atomic percentage conc adopting vacuum induction melting to obtain is machined into through hole, as the skin of compound billet, be that the NiW alloy solid bar of 9% is as the sandwich layer of compound billet using adopting the W atomic percentage conc prepared of vacuum induction melting, be inserted in outer NiW compo pipe by sandwich layer NiW alloy solid bar, the diameter of core alloys rod equals the internal diameter of outer layer alloys pipe;
(2), the hot rolling of compound billet
The compound billet of mechanical combination in step (1) is carried out hot rolling process, and hot-rolled temperature is 1300 DEG C of insulation 10h, and the pass deformation of hot rolling is 15% ~ 25%, and total deformation is 70% ~ 80%, obtains the cold rolling front initial recombination billet of aximal deformation value;
(3), the cold rolling and dynamic recrystallization treatment of compound billet
Compound billet hot rolling obtained carries out cold rolling, pass deformation is 1% ~ 3%, total deformation is 97%, in whole cold-rolled process, total deformation is cold rolling before 70% must ensure that rolling direction is constant after every time, upper and lower surface or the oppositely rolling of base band can not be put upside down, finally adopt the dynamic recrystallization treatment of 1100 ~ 1250 DEG C of insulation 150min to obtain the NiW alloy composite baseband of low magnetic, high strength, strong cubic texture.
Because the Ni9%W alloy bar prepared by sandwich layer vacuum induction melting is inserted into after in NiW compo pipe prepared by outer vacuum induction melting, only by mechanical bond together, direct cold rolling can cause cracking, the present invention adds high-temperature hot roll process before cold rolling can increase mechanical bonding strength between skin and sandwich layer, and make to produce atomic diffusion between skin and sandwich layer, metallurgical binding is produced in interface, simultaneously, the cast structure that hot rolling improves in outer and sandwich layer ingot casting as a kind of dynamic recrystallization forms equiax crystal, more easily obtain strong cubic texture, and control the rolling mode in cold rolling early stage, effectively can avoid the cold rolling delamination caused of follow-up aximal deformation value like this.
