Description
Technical field
The present invention relates to a kind of titanium alloy composite material, more particularly to a kind of high intensity, the type alpha+beta with superior cost performance
Titanium alloy composite material.
Background technology
Alpha and beta type titan alloy is widely used in the fields such as Aeronautics and Astronautics, automobile, glof club head, bicycle, its typical case
Representative is the Ti-6Al-4V alloys that the U.S. in 1954 succeeds in developing.Ti-6Al-4V alloys have good combination property, at present
Ti-6Al-4V alloy usage amounts have accounted for more than half of whole titanium alloys.But the cost performance of Ti-6Al-4V alloys is not high enough,
About 350 DEG C of operating temperature when long, V content higher causes the on the high side of alloy in alloy, its room temperature strength and elevated temperature strength
Also further raising is needed, these limit further genralrlization application of the Ti-6Al-4V alloys in defence and military and civilian goods.
The content of the invention
The technical problems to be solved by the invention are to provide the high intensity that a kind of cost performance is substantially better than Ti-6Al-4V alloys
Alpha and beta type titan alloy composite, operating temperature is up to 450 DEG C when its is long.
Technical scheme is as follows：
A kind of alpha and beta type titan alloy composite, it is characterised in that contain by weight percentage：Aluminium 7~8.5, vanadium 0.5~
1.5th, molybdenum 1~3, chromium 1~3, iron 0.3~1, rare earth element 0.05~0.1, (SiC fibers+BC) 1.0~2.0, remaining be titanium and
Inevitable impurity.
Titanium alloy composite material of the present invention can be typically prepared method production using titanium alloys such as founding press-working methods, can
Realize industrial mass production.Carbon, hydrogen, oxygen, the total weight percent of nitrogen are no more than 0.25 in control impurity.The v element
Added in aluminium vanadium intermediate alloy form, the molybdenum element is added in aluminium molybdenum intermediate alloy form, to ensure the accurate of alloying component
Property and uniformity are so that it is guaranteed that the uniformity of alloy material performance.The rare earth element is added in mixed rare earth of lanthanum and cerium form.
Aluminium content is high compared with Ti-6Al-4V in alpha and beta type titan alloy of the present invention, the normal temperature of the raising for raising alloy of aluminium content
There is positive effect with elevated temperature strength, reduction proportion, increase elastic modelling quantity；Vanadium, molybdenum, chromium, iron are beta stable element, with Ti-6Al-4V
Compare, the addition of vanadium is greatly reduced；The addition of appropriate rare earth element is played a part of to improve titanium alloy surface antioxygenic property.
The room temperature tensile intensity and yield strength ratio Ti-6Al-4V of alpha and beta type titan alloy of the present invention improve more than 30%, and elevated temperature strength is also bright
Aobvious to be better than Ti-6Al-4V, density is suitable with Ti-6Al-4V, thus titanium alloy of the present invention than Ti-6Al-4V alloy with more superior
Cost performance, wide market.
Specific embodiment
Embodiment 1
Titanium alloy composite material of the present invention is manufactured using founding press-working method, alloying component dispensing is specifically pressed, alloy
Percentage by weight is constituted：Aluminium 8.0, vanadium 1.0, molybdenum 2.0, chromium 2.0, iron 0.5, rare earth element 0.08, (SiC fibers+BC) 1.5,
Remaining is titanium and inevitable impurity.Above alloying element composition electrode is melted using secondary vacuum consumable smelting into ingot casting
Refining vacuum level requirements are less than 1Pa.In fusion process, v element is added in aluminium vanadium intermediate alloy form, and molybdenum element is with aluminium molybdenum
Between alloy form add, rare earth element with mixed rare earth of lanthanum and cerium form add, and strictly control carbon, hydrogen, oxygen, the gross weight of nitrogen
Amount percentage is no more than 0.25.Ingot casting carries out cogging forging at 1000~1200 DEG C, is made slab.Then hot rolling, hot rolling are carried out
Temperature carries out cold rolling between 800~1000 DEG C, finally, and titanium alloy composite material plate is obtained after the annealed treatment of cold-reduced sheet.
Obtained titanium alloy sheet (thickness is 3mm) is tested through national non-ferrous metal research institute, tensile strength is at room temperature
1270MPa, yield strength is 1200MPa, and elongation after fracture is 10.0%, and Rockwell hardness number is 42.Compare titanium alloy of the present invention
With the Ti-6Al-4V alloys of same thickness annealing sheet material combination property at room temperature, 1 is the results are shown in Table.
The titanium alloy of the present invention of table 1 and Ti-6Al-4V Alloy At Room Temperature Performance comparisions
| Titanium alloy title | Yield strength (MPa) | Tensile strength (MPa) | Elongation (%) | Hardness (HRC) | Density (g/cm3) |
| Ti-6Al-4V | 870 | 925 | ≥10 | 36 | 4.5 |
| Titanium alloy of the present invention | 1200 | 1270 | 10 | 42 | 4.45 |
The density that can be seen that titanium alloy composite material of the present invention by data in table is suitable with Ti-6Al-4V, room temperature strength
Ti-6Al-4V is much better than, tensile strength and yield strength improve more than 30% than Ti-6Al-4V, and Plastic phase is worked as.The present invention
Titanium alloy composite material aluminium content is higher than Ti-6Al-4V and content of vanadium is much lower, and its cost performance is substantially better than Ti-6Al-4V.Separately
Outward, the tensile strength for being measured at 440 DEG C of temperature by the present embodiment gained titanium alloy sheet is 960MPa, and Ti-6Al-4V is in temperature
Tensile strength at 400 DEG C of degree is only 645MPa, illustrates that the elevated temperature strength of titanium alloy of the present invention is also significantly better than Ti-6Al-4V.
