AMS 4911 Titanium Alloy, Sheet, Strip, and Plate 6Al - 4V Annealed (Composition similar to UNS R56400)

1 .1 Form

This specification covers a titanium alloy in the form of sheet, strip, and plate up through 4.000 inches (101.60 mm) inclusive in thickness (See 8.5).

1 .2 Application

These products have been used typically for parts requiring strength up to 750 °F (399 °C), but usage is not limited to such applications.

1 .2.1 Certain processing procedures and service conditions may cause these products to become subject to stress-corrosion cracking; ARP982 recommends practices to minimize such conditions.

3.1 Composition

Shall conform to the percentages by weight shown in Table 1; carbon shall be determined in accordance with ASTM E1941, hydrogen in accordance with ASTM E1447, oxygen and nitrogen in accordance with ASTM E 1409, and other

elements in accordance with ASTM E539 or ASTM E2371. Other analytical methods may be used if acceptable to the purchaser.

3.3 Condition

The product shall be supplied in the following condition:

3.3.1 Sheet and Strip

Hot rolled with or without subsequent cold reduction, annealed, descaled, and leveled, having a surface appearance comparable to a commercial corrosion-resistant steel sheet No. 2D finish (See 8.2).

3.3.2 Plate

Hot rolled, annealed, descaled, and flattened, having a surface appearance comparable to commercial corrosion-

resistant steel No. 1 finish (See 8.2). Plate product shall be produced using standard industry practices for the production of the plate to the procured thickness. Bar, billet, forgings, or forging stock shall not be substituted for the plate.

3.4 Annealing

The product shall be annealed by heating to a temperature within the range 1 300 to 1 650 °F (704 to 899 °C), holding at the selected temperature within ±25 °F (±1 4 °C) for a time commensurate with product thickness and the heating equipment and procedure used, and cooling at a rate which will produce product meeting the requirements of 3.5. Pyrometry shall be in accordance with AMS2750.

3.5 Properties

The product shall conform to the following requirements and also shall meet the requirements of 3.5.1 and 3.5.2 after being reheated in air to 1325 °F ± 1 5 (718 °C ± 8), held at heat for 20 minutes ± 2, cooled at a rate equivalent to an air cool or slower.

3.5.1 Tensile Properties

Shall be as specified in Table 2, determined in accordance with ASTM E8 / E8M with the rate of strain set at

0.005 inch/inch/minute (0.005 mm/mm/minute) and maintained within a tolerance of ±0.002 inch/inch/minute

(0.002 mm/mm/minute) through the 0.2% offset yield strain.

3.5.2 Bending

Product under 0.1875 inch (4.762 mm) in nominal thickness shall have a test sample prepared nominally 0.750 inch(19.06 mm) in width, with its axis of bending parallel to the direction of rolling. The sample shall be bend tested in conformance with the guided bend test defined in ASTM E290 through an angle of 105 degrees. The test fixture supports shall have a contact radius 0.010 inch (0.25 mm) minimum, and the plunger shall have a radius equal to the bend factor shown in Table 3 times the nominal thickness. Examination of the bent sample shall not show evidence of cracking when examined at 1 5 to 25X magnification.
