normalizing, hardening, and tempering. In the heat-treatment of aluminum alloys, only two processes are included: the hardening and toughening process and the softening process. The hardening and toughening process is called heat-treating, and the softening process is called ... shock and fatigue resistance. It is essential that materials used for critical parts be resistant to these stresses. Heat-treatment is a series of operations involving the heating and cooling of metals in the solid state. Its purpose…

placed in a separate container and stored for reheat-treatment. Heat-treatment of rivets may be repeated a number of times if done properly. Proper heating times and temperatures are shown in Figure 7-36. Most metals, and therefore aircraft ... without an iron base, do not rust, but a similar process known as corrosion takes place. The salt in moist air (found in the coastal areas) attacks the aluminum alloys. It is a common experience to inspect the rivets…
