Definitions
- Titanium-base alloys used for structural purposes in the aircraft and aerospace industries should possess several important characteristics.
- the alloy should be produced readily as a mill product, such as sheet, strip, plate, bar, billet, tubing or wire, by melting, forging, rolling or other commercial metalworking processes.
- Preferably final production and fabrication of sheet, strip, tubing and wire are performed at room temperature for reasons of efficiency and economy and to attain a desirable surface finish and properties.
- the alloy in its annealed or softened state the alloy should have sufficient ductility (l percent minimum elongation in 2 inches) to allow considerable forming at room temperature. It should be possibk to bend a sheet of the alloy to a radius less than twice its thickness without breaking the sheet.
- the least radius to which a sheet can be bent is referred to as its minimum bend radius" (MBR) and is usually expressed as a ratio of radius-tothickness.
- MRR minimum bend radius
- the alloy should respond to heat treatment and achieve heat-treated yield strengths greater than I60 Ks.i. with useful toughness and ductility (4 percent minimum elongation in 2 inches), which properties it should retain afier prolonged exposure to temperatures up to 600" F. under allowable design stresses.
- the alloy also should have high strengthto-weight ratios which are needed in weight-critical structures.
- titanium metal may exist as an alpha phase, a beta phase, or an alpha-beta structure which is a mixture of the two phases.
- the pure metal assumes the alpha phase, which has a closely packed hexagonal crystalline structure.
- the pure metal assumes the beta phase, which has a body-centered cubic crystalline structure.
- the beta phase can be retained wholly or in part at room temperature by adding to titanium certain alloying elements known as beta stabilizers. These may be either beta-eutectoid elements, such as iron, manganese, chromium, cobalt or nickel, or beta-isomorphous elements, such as vanadium, molybdenum, columbium or tantalum.
- beta stabilizers may be either beta-eutectoid elements, such as iron, manganese, chromium, cobalt or nickel, or beta-isomorphous elements, such as vanadium, molybdenum, columbium or tantalum.
- beta-eutectoid elements such as
- An object of our invention is to provide a metastable allbeta titanium-base alloy which possesses the desirable characteristics hereinbefore listed.
- a further object is to provide an alloy which has these characteristics and can be produced with conventional mill equipment and is sufficiently ductile to be cold-worked and finished at room temperature, yet can be simply heat treated to medium and high strengths.
- a further object is to provide an alloy of the foregoing characteristics in which we control the average valence electron density (VED) to a critical range (about 4. i 5 to 4.30).
- VED average valence electron density
- FIG. 1 is a typical phase diagram of a titanium-beta-eutectoid element system
- F IG. 2 is a graph illustrating how we determine the theoretical maximum content of beta-eutectoid elements in our alloy.
- Our alloy contains one or more of the beta-eutectoid elements iron, manganese, chromium or cobalt. These elements have advantages for stabilizing the beta phase of titanium alloys, since they are compatible with the melting process (no master alloys required), they are relatively lightweight compared with the beta-isomorphous elements, and they are strong beta stabilizers. However, if they are added to a titanium alloy in excessive quantities, compounds form and ductility is lost. Preferably we include in our alloy beta-eutectoid elements near the maximum quantities that do not form compounds. We look to the phase diagrams to determine the content we can safely include.
- FIG. I shows, some known percentage of a beta-eutectoid element added to titanium forms a eutectoid at some known temperature, indicated at point b.
- the percentage and temperature of course are different for each beta-eutectoid element, but all follow a similar pattern.
- Line a-b represents the boundary between the beta phase and the beta-plusFcompound.
- FIG. 2 shows the extrapolation for the five beta-eutectoid elements iron, manganese, chromium, cobalt and nickel.
- the extrapolated curves for the first four reach room temperature at atomic percentages of the element ranging from about 3.5 to 8.5, but the extrapolated curve for nickel never reaches room temperature.
- Our alloy also contains aluminum in proportions of about L75 to 7 atomic percent.
- Aluminum is an alpha promoter and inhibits retention of the beta phase at room temperature. We overcome this effect of aluminum in our alloy by our inclusion of large quantities of beta-eutectoid and beta-isomorphous elements already described.
- Our alloy also may contain at least one of the neutral elements tin and zirconium in the following approximate proportions:
- trons as have the neutral alloying elements zirconium and tin.
- Aluminum has 3 valence electrons, and as already mentioned is an alpha stabilizer, which retards formation of the beta phase.
- the heta-isomorphous elements vanadium, columbium 2.5% Fe or 3.595 H1: or 5.55 Cr or and tantalum have 5 valence electrons while molybdenum has 122: 6.
- the beta-eutectoid elements which we can use have valence m-za electrons as follows:
- An alloy as defined in claim 1 containing in addition at least one neutral element selected from the group which consists of tin and zirconium in amounts up to approximately 3 percent of the alloy.
- An alloy as defined in claim 3 containing in addition at least one neutral element selected from the group consisting of tin and zirconium in amounts of approximately 1.5 to 2.5 percent of the alloy.
