Nickel-copper-aluminum alloy shall be produced by the electric furnace (EAF) or vacuum induction furnace (VIM) process and further refined by any process proved adequ

27、ate to pass the slow strain rate tensile test (see 3.4 and 4.3.6). Casting may be by ingot or continuous cast methods. Cast ingots or billets shall be hot worked to a fine uniform grain structure. Final processing shall be by hot working or cold working, and heat treating. 3.1.1 Forgings as final pr

28、oduct. For all forgings other than bar or rod, a forging sketch shall be prepared when specified (see 6.2). Forgings with final forged diameter or distance across parallel surfaces of 4 inches or greater shall be to such a configuration that they can be ultrasonically inspected 100 percent by volume

29、 with three directional coverage. 3.1.2 Heat treatment.

Solution treating shall be accomplis

31、hed by holding at a minimum temperature of 1600F, followed by water quenching. The time at temperature must be such that the entire volume of material is heated to the solution treating temperature. 3.1.2.2 Age hardening.

The uni

37、formity of grain size shall be determined for bar and rod as specified in 4.3.5. Plate, sheet, strip, and wire shall be excluded from this requirement. 3.6 Recovered materials.
