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.
