Description / Abstract:
Purpose
This specification covers the engineering requirements for heat
treatment of magnesium alloy castings and for parts machined from
castings.
Application
When AMS2768 is specified and specific heat treat processing
instructions are included in the material specification, the
equipment and control requirements of AMS2768 shall apply. For
alloys not specifically covered, the applicable provisions of this
specification shall be invoked but temperatures, times, and quench
procedures shall be as specified by the cognizant engineering
organization.
It is permissible, for specific parts, to use equipment,
practices and test methods which conformed to AMS-M-6857 and were
previously acceptable to the purchaser.
