1.1 Purpose
This specification covers the heat treatment of titanium and titanium alloy mill products (raw material), including wrought
and cast products, by material producers. This specification also covers furnace equipment requirements, test
procedures, and general information for heat treating procedures, heat treating temperatures, and material test
procedures for the heat treatment of titanium and titanium alloys. It also describes procedures that, when followed, have
produced the desired properties within the limitations of the respective alloys.
1.2 Heat Treatments
The heat treatments covered by this specification are:
Anneal Solution heat treatment
Beta anneal Beta solution heat treatment
Recrystallization anneal Age
Duplex anneal Stress relief
1.3 Alloys
In addition to Commercially Pure Titanium (Ti40, Ti55, and Ti70), the following titanium alloys are covered by this
specification:
