本手册的主要目的是为常用金属材料和接头提供基于统计的设计值来源。此外，还包括航空航天结构设计所需的其他机械和物理性能。本章包含用于飞机和导弹应用的锻造和铸造镁合金的工程特性和特征。镁是一种轻质结构金属，可以通过合金化，在某些情况下通过热处理或冷加工，或通过两者进行强化。

The primary purpose of this Handbook is to provide a source of statistically based design values for commonly used metallic materials and joints. Additionally, other mechanical and physical properties needed for the design of aerospace structures are included.This chapter contains the engineering properties and characteristics of wrought and cast magnesium alloys used in aircraft and missile applications. Magnesium is a lightweight structural metal that can be strengthened greatly by alloying, and in some cases by heat treatment or cold work or by both.
