Description
Technical field
The invention belongs to titanium steel composite board prepares manufacture field, be related to a kind of titanium steel composite board with IF steel as intermediate layer and
Its manufacture method.
Background technology
Titanium has good physics, chemical property and mechanical performance, but its smelting technique is complicated, and production cost is high, therefore
The price of titanium is expensive, largely limits popularization and the application of titanium.Titanium is compounded in other metals (as steel, copper, aluminum etc.)
Together, make metallic composite, both can play the excellent properties of titanium, cost can be substantially reduced again, thus in recent years to class
A lot of like the research of material, wherein titanium-steel composite material is with its high intensity, excellent corrosion resisting property and significant economic benefit
It is widely used in the industrial departments such as chemical industry, oil.
Because the metallicity of titanium is active, brittlement phase will be formed when being connected with most metals on interface.By titanium-ferrum Binary-phase
Figure understands, ferrum and titanium easily generate intermetallic compound, such as TiFe, TiFe2Deng, due to intermetallic compound have larger crisp
Property make combination interface brittle, be easily caused cracking in the presence of stress, so that bond strength is declined.Titanium is when temperature is for 1155K
Undergo phase transition, existed with body-centered cubic lattic β-Ti form during high temperature, be the α-Ti of solid matter cubic lattice when temperature is relatively low.Ferrum exists
Solid solubility very little in α-Ti, at room temperature only 0.05%～0.1%, it is less than 0.5% under eutectoid temperature.Ferrum is β-Ti
Stable element, the solid solubility ratio in β-Ti is big in α-Ti, in eutectic temperature 1355K, solid solubility in β-Ti for the ferrum
Reach maximum 25%.After solid solution ferrum in β-Ti, its phase point temperature can be made to reduce, when in β-Ti, iron content reaches
During certain value, β-Ti will be retained to room temperature, with the increasing further of iron content in β-Ti, in cooling procedure, it will
Cause supersaturation in titanium for the ferrum, and then exceed its solid solubility in titanium and form intermetallic compound.Reduce compound life
The main method becoming is to insert suitable metal between titanium and steel to do intermediate layer, and then stops the mutual expansion of the elements such as titanium, ferrum
Dissipate, common for metallic plates such as insertion copper, nickel, niobiums, but introduce new chemical combination while suppressing the Elements Diffusion such as titanium, ferrum
Thing.
Content of the invention
For the titanium/iron compound that can generate brittlement phase on existing titanium steel composite board preparation process median surface, the present invention carries
It is the method that titanium steel composite board is prepared in intermediate layer for a kind of IF steel.The method with IF steel as intermediate layer, according to raw material steel grade
Difference, select special rolling mill practice.The inventive method does not introduce other elements, and carbon can be hindered to spread to titanium side, with
When form the moderate TiC layer of a layer thickness, both will not make composite plate performance degradation, the formation of TiFe phase can have been suppressed, finally again
Make the titanium steel composite board preparing functional.
