Abstract
The invention discloses an alpha plus beta type titanium alloy. The titanium alloy comprises the following components in percentage by weight: 7 to 8.5 percent of aluminum, 0.5 to 1.5 percent of vanadium, 1 to 3 percent of molybdenum, 1 to 3 percent of chromium, 0.3 to 1 percent of iron, 0.05 to 0.1 percent of rare earth element, the balance being titanium and inevitable impurities. The titanium alloy can be manufactured by common manufacturing methods for the titanium alloy such as the fusion casting pressure processing method and the powder metallurgic method. The total weight percentage of carbon, hydrogen, oxygen and nitrogen in the impurities is no more than 0.25 percent, and the vanadium is added in the form of aluminum-vanadium intermediate alloy, the molybdenum is added in the form of aluminum-molybdenum intermediate alloy, and the rare earth is added in the form of lanthanum-cerium mixed rare earth. Compared with Ti-6Al-4V, the room-temperature tensile strength and yield strength of the titanium alloy are improved by more than 30 percent, the high-temperature strength is also obviously enhanced, and the density and the cost are slightly lowered, so that the titanium alloy has more desirable performance-to-price ratio and wider market prospect.
Description
Technical field
The present invention relates to a kind of titanium alloy, the alpha and beta type titan alloy that relates in particular to a kind of high strength, has the superiority price ratio.
Background technology
Alpha and beta type titan alloy is widely used in fields such as Aeronautics and Astronautics, automobile, golf club head, bike, and its typical case representative is the Ti-6Al-4V alloy that the U.S. in 1954 succeeds in developing.The Ti-6Al-4V alloy has good comprehensive performances, and Ti-6Al-4V alloy usage quantity has accounted for the over half of whole titanium alloys at present.But the cost performance of Ti-6Al-4V alloy is not high enough, working temperature is about 350 ℃ when long, V content higher in the alloy causes the on the high side of alloy, its room temperature strength and hot strength also remain further to be improved, and these have limited Ti-6Al-4V alloy further applying in defence and military and civilian goods.
Summary of the invention
Technical problem to be solved by this invention provides the high strength alpha and beta type titan alloy that a kind of cost performance obviously is better than the Ti-6Al-4V alloy, and working temperature can reach 450 ℃ when it was long.
Technical scheme of the present invention is as follows:
A kind of alpha and beta type titan alloy is characterized in that containing by weight percentage: aluminium 7～8.5, vanadium 0.5～1.5, molybdenum 1～3, chromium 1～3, iron 0.3～1, rare earth element 0.05～0.1, all the other are titanium and unavoidable impurities.
Titanium alloy of the present invention can adopt general preparation method's production of titanium alloys such as founding press-working method or powder metallurgic method.The total weight percent of carbon, hydrogen, oxygen, nitrogen is no more than 0.25 in the control impurity.Described v element adds with aluminium vanadium master alloy form, and described molybdenum element adds with aluminium molybdenum master alloy form, thus the consistence of guaranteeing the alloy material performance with the accuracy of guaranteeing alloying constituent and homogeneity.Described rare earth element adds with the mixed rare earth of lanthanum and cerium form.
Aluminium content is than the Ti-6Al-4V height in the alpha and beta type titan alloy of the present invention, and the raising of aluminium content has positive effect for the normal temperature that improves alloy and hot strength, reduction proportion, increase Young's modulus; Vanadium, molybdenum, chromium, iron are beta stable element, compare with Ti-6Al-4V, and the addition of vanadium greatly reduces, thereby have reduced the manufacturing cost of titanium alloy; The effect that improves the titanium alloy surface antioxidant property is played in the interpolation of an amount of rare earth element.The room temperature tensile strength of alpha and beta type titan alloy of the present invention and yield strength ratio Ti-6Al-4V improve more than 30%, hot strength also obviously is better than Ti-6Al-4V, density and cost are lower slightly than Ti-6Al-4V, therefore titanium alloy of the present invention has more superior cost performance than Ti-6Al-4V alloy, and market outlook are wide.
Embodiment
Embodiment 1
Adopt founding press working manufactured titanium alloy of the present invention, specifically by the alloying constituent batching, the weight percent of alloy consists of: aluminium 8.0, and vanadium 1.0, molybdenum 2.0, chromium 2.0, iron 0.5, rare earth element 0.08, all the other are titanium and unavoidable impurities.Above alloying element is formed electrode adopt the secondary vacuum consumable smelting to become ingot casting, melting vacuum tightness requires to be lower than 1Pa.In fusion process, v element adds with aluminium vanadium master alloy form, and molybdenum element adds with aluminium molybdenum master alloy form, and rare earth element adds with the mixed rare earth of lanthanum and cerium form, and the strict total weight percent of controlling carbon, hydrogen, oxygen, nitrogen element is no more than 0.25.Ingot casting carries out cogging at 1000～1200 ℃ and forges, then 900～1000 ℃ carry out low temperature repeatedly pier pull out, make slab.Then carry out hot rolling, hot-rolled temperature is between 800～1000 ℃, and hot-rolled sheet obtains the hot rolling titanium alloy plate after anneal.
Through the test of national ferrous materials test center, tensile strength is 1270MPa under the room temperature with the titanium alloy sheet (thickness is 3mm) that makes, and yield strength is 1200MPa, and elongation after fracture is 10.0%, and Rockwell hardness number is 42.Relatively the Ti-6Al-4V alloy of titanium alloy of the present invention and same thickness annealing sheet material over-all properties at room temperature the results are shown in Table 1.
Table 1 titanium alloy of the present invention and Ti-6Al-4V alloy room-temperature property are relatively
| The titanium alloy title | Yield strength (MPa) | Tensile strength (MPa) | Elongation (%) | Hardness (HRC) | Density (g/cm 3) |
| Ti-6Al-4V | 870 | 925 | ≥10 | 36 | 4.5 |
| Titanium alloy of the present invention | 1200 | 1270 | 10 | 42 | 4.4 |
By data in the table as can be seen, the density of titanium alloy of the present invention is lower slightly than Ti-6Al-4V, and room temperature strength is much better than Ti-6Al-4V, and tensile strength and yield strength all improve more than 30% than Ti-6Al-4V, and plasticity is suitable.Titanium alloy aluminium content of the present invention is than Ti-6Al-4V height and content of vanadium is much lower, so its cost is lower slightly than Ti-6Al-4V, its cost performance obviously is better than Ti-6Al-4V.In addition, the tensile strength that is recorded under 440 ℃ of temperature by present embodiment gained titanium alloy sheet is 960MPa, and the tensile strength of Ti-6Al-4V under 400 ℃ of temperature only is 645MPa, illustrates that Titanium Alloys at High Temperature intensity of the present invention also obviously is better than Ti-6Al-4V.
