AMS 2774, “Heat Treatment, Wrought Nickel Alloy and Cobalt Alloy Parts,” has just been revised as a new 2012 Revision D and it’s available now in paper and pdf format from Document Center Inc. This specification specifies the engineering requirements for heat treatment, by part fabricators (users) or their vendors or subcontractors, of parts made of wrought nickel or cobalt alloys, of raw materials during fabrication, and of fabricated assemblies in which wrought nickel or cobalt alloys are the primary structural components.
Detailed heat treating instructions are specified for age-hardenable (precipitation-hardenable) and non-age-hardenable alloys which are listed in section 8.2. However, AMS 2774D may also be used for other alloys provided that temperatures, soaking times, and cooling requirements are specified by the cognizant engineering organization.
Heat treatments covered by this specification are as follows:
Solution Treating (Section 8.4.7)
Annealing (Section 8.4.8)
Stabilization Annealing (Section 8.4.10)
Interstage Annealing (Section 8.4.13)
Stabilization (Section 8.4.11)
Precipitation (Section 8.4.12)
Equalization (Section 8.4.14)
Stress Relief (Section 8.4.9).
While the materials, methods, applications, and processes described or referenced in AMS 2774 may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
