  ]. As an example, Figure 6 shows the residual stress and. cold work vs. depth measured by X-ray diffraction (XRD) on. thermally exposed shot peened and LPB treated Inconel 718. Compression produced by shot peening is dramatically. reduced, at and near the surface, as a result of the 525°C and. 600°C thermal...
• Engineering Characteristics of Drawn Filled Nitinol Tube (.pdf)
  composite wires were evaluated by looking at several key mechanical parameters commonly. used in the industry. The effects studied were the loading plateau stress, unloading plateau stress, permanent set,. stress strain hysteresis, and bending stiffness. This paper does not attempt to quantify fatigue...
• General Characteristics of DFT(R) Composite Wire (.pdf)
  ® composite wire was first introduced in 1985 and has since been refined. continually. This document provides information relating to general characteristics and. properties that can be obtained utilizing DFT technology. Some topics include ultimate. strength properties, electrical properties, fatigue...
• Controlled-expansion alloys for turbine engines
  ). Fatigue resistance is also important in controlled thermal expansion alloys because aircraft engines often produce vibrational and cyclic thermal stresses. Rotating beam fatigue tests show that Thermo-Span has a higher fatigue strength than CTX-909. Thermal stability, of course, is critical...
• Adhesives
  to a structure. A related characteristic, fatigue resistance, can be improved by the ability of such adhesives to withstand cyclic strains and shock loads without cracking. In a properly designed joint, the adherends generally fail in fatigue before the adhesive fails. Adhesives are sometimes used...
