BATTELLE MMPDS-07 CHAPTER 5

Abstract

<strong>GENERAL</strong> <br>This chapter contains the engineering properties and related characteristics of titanium and titanium alloys used in aircraft and missile structural applications. <br>General comments on engineering properties and the considerations relating to alloy selection are presented in Section 5.1. Mechanical- and physical-property data and characteristics pertinent to specific alloy groups or individual alloys are reported in Sections 5.2 through 5.5. <br>Titanium is a relatively lightweight, corrosion-resistant structural material that can be strengthened greatly through alloying and, in some of its alloys, by heat treatment. Among its advantages for specific applications are: good strength-to-weight ratio, low density, low coefficient of thermal expansion, good corrosion resistance, good oxidation resistance at intermediate temperatures, good toughness, and low heattreating temperature during hardening, and others.
