Abstract
The invention discloses a titanium alloy thin plate treatment method. The titanium alloy thin plate treatment method is characterized in that under the conditions of a vacuum degree of 1.33*10<-2> to 1.33*10<-4>Pa and a temperature of 704-800 DEG C, titanium and titanium alloy thin plates are pressed on a platform by a pressing flat plate in a special-purpose horizontal vacuum heating furnace under the pressing pressure of 400kg/m<2> for continuous 2-18h, then are cooled to a temperature of 600+/-20 DEG C, and then are filled with cooling gas in 30-90min and are fast cooled to below 400-350 DEG C. The titanium alloy thin plate obtained by the titanium alloy thin plate treatment method has Ti-Al-Fe strength 200MPa higher than pure Ti material strength, has an isometric microscopic structure, has the superplastic performances of the common alpha+beta titanium alloy, has a wide superplastic deformation temperature range and can be processed and molded easily.
Description
Technical field
The present invention relates to titanium alloy steel making field, especially about a kind of surface treatment method of titanium-alloy thin-plate.
Background technology
Titanium alloy is during as trolley part materials'use, its feature is as follows: half that tensile strength and yield strength are large, fatigue strength is large, density is little, Young's modulus is approximately steel, thermal expansivity are low, be approximately stainless steel and aluminium half, non magnetic, thermal conductivity is low, easily produce sintering, environmentally safe etc.In automobile industry, with after titanium, can greatly alleviate vehicle weight, reduce its fuel consumption, reduce noise and the vibration of engine, protection of the environment and reduction noise.Utilize titanium alloy to make auto parts machinery, not only can weight reduction, save fuel oil, and power transmission is effective, contributes to good dynamic performance, operational stability.Reliability is high, increases the service life.Automobile titanium is a very huge market, and according to design and material behavior, the application of titanium on automobile is mainly distributed on engine components and vehicle chassis component.In engine system, with titanium, can make the elements such as valve, valve spring, valve spring bearing and connecting rod, the improvement of performance shows the minimizing of torque, output rating and interconnecting piece distortion.
Summary of the invention
For above problem; the object of the present invention is to provide a kind of surface treatment method of titanium-alloy thin-plate; to adopt new formula and gas shield technique; make nitrogen and oxygen from titanium or titanium alloy member surface to inner solid solution diffusion, be suitable for the high strength titanium alloy as the material of various adornments, the said products of being made by this alloy.
Technical scheme of the present invention is achieved in the following ways: a kind of surface treatment method of titanium-alloy thin-plate, it is characterized in that: be that in a special horizontal vacuum furnace, to keep vacuum tightness be 1.33 * 10-2～1.33 * 10-4 handkerchief, temperature is under 704 ℃～800 ℃ conditions, titanium or titanium alloy thin plate is suppressed so that ballast is dull and stereotyped on platform, pressing pressure is greater than under 400 kg/m 2 conditions and continues 2～18 hours, then cooling, it being filled with in 30～90 minutes to cooling gas when being cooled to 600 ℃ ± 20 ℃ is quickly cooled to below 400～350 ℃.
The present invention, can make Ti-Al-Fe intensity exceed the about 200MPa of pure titanium material, the axle microscopic structure such as has, the same with general alpha+beta titanium alloys, have superplastic behavior, and the temperature range of superplastic deformation is very wide, is easy to forming process.
Embodiment
A kind of surface treatment method of titanium-alloy thin-plate, it is characterized in that: be that in a special horizontal vacuum furnace, to keep vacuum tightness be 1.33 * 10-2～1.33 * 10-4 handkerchief, temperature is under 704 ℃～800 ℃ conditions, titanium or titanium alloy thin plate is suppressed so that ballast is dull and stereotyped on platform, pressing pressure is greater than under 400 kg/m 2 conditions and continues 2～18 hours, then cooling, it was filled with in 30～90 minutes to cooling gas when being cooled to 600 ℃ ± 20 ℃ and is quickly cooled to below 400～350 ℃.
