Aerospace Residual Stress can be of great importance to the aerospace industry. By keeping track of the residual stresses in various aircraft components, it is possible to monitor the physical integrity of the part and potentially prevent catastrophic failure. MaterialsTesting’s nondestructive techniques can quickly and easily provide a direct measurement of the residual stress state of a variety of elements where it may be of concern. Several examples include: Skins, Landings Gears, Fastener Holes, Engine Components (turbine/compressor blades, stators, disks), etc. All residual stress measurements are done in accordance with ASTM E915, ASTM E2860 and SAE HS-784.
Retained austenite is also significant for many aerospace bearing applications where tight dimensional tolerances are critical. These parts must typically conform to specifications citing a low retained austenite content to prevent failures due to volume-related phase change. The Materials Testing Division uses reflections from four distinct sets of atomic planes to provide a fast and accurate determination of the austenite content in a steel part. All retained austenite measurements are done in accordance with ASTM E975 & SAE SP-453.Request a Quote
